Is it a single measurement or a set

of measurements?

Uncertainty is half the graduation of the instrument used

Present your answer as:Value ± Uncertainty Units

Eg: 64 ± 0.5 mm.

Uncertainty is the difference between the average reading and the biggest or smallest value obtained, whichever is

the greater or half the range of readings.

Present your answer as:Average ± Uncertainty Units

Eg: 64 ± 3 mm

Are the measurements all the same?

Single

Topic 1: Calculating % UncertaintyThe percentage uncertainty in a measurement can be calculated using:

Percentage uncertainty =Uncertainty of measurement

Measurement× 100%

Rules for combining percentage uncertainties

Rule 1: Multiplying a measurement by a constant does not change the percentage uncertaintyRule 2: If you multiply, or divide, two or more measurements, you need to add their percentage uncertainties to find the total percentage uncertaintyRule 3: If a measurement is raised to a power, its percentage uncertainty is multiplied by that powerRule 4: If you add or subtract two measurements, the absolute uncertainty is the sum of each contributing absoluteuncertainty.

Percentage uncertainty =Half the range

Mean× 100%

Percentage difference =Difference between result and known value

Known value× 100%

Resultswith % uncertainties< 5% are deemed

repeatable

Topic 1: Combining UncertaintiesSummary of the rules for finding the uncertainty of a quantity found by combining other values in a formula e.g.Can of length L = 115 mm ± 2 mm, diameter d = 66.0 ± 0.6 mm. Find the volume of the can and the uncertainty:

1. Convert the uncertainties you have been given to percentage uncertainties (%U)

%𝑈 𝑖𝑛 𝐿 =2

115× 100% = 1.7% % 𝑈 𝑖𝑛 𝑑 =

0.6

66.0× 100% = 0.9%

2. Find the value you have been asked to calculate, one step at a time. At each step calculate the percentage uncertainty of each quantity you find using the rules on the previous slider = 𝑑 ÷ 2 𝑟 = 66 ÷ 2 = 33𝑚𝑚 = 0.33𝑚Using Rule 1: %U on r =0.9%

𝐴 = 𝜋𝑟2 𝐴 = 𝜋 × 0.332 = 0.0034𝑚2

Using Rules 1 and 2: %U on A = %U on r + %U on r = 0.9% + 0.9% = 1.8%

𝑉 = 𝐿 × 𝐴 𝑉 = 0.115 × 0.0034 = 3.91 × 10−4𝑚3

Using Rule 2: %U on V = %U on L + %U on A = 1.7% + 1.8% = 3.5%

3. Convert the final percentage uncertainty back to an absolute uncertainty3.5% of 3.91 × 10−4𝑚3 = 1.4 × 10−5𝑚V = 39.1 ± 1.4 × 10−5𝑚

Weight = mass x gravitational field strength

W = m g

Force = mass x acceleration

F = m a

g = F / m

The falling object will accelerate until the weight is balanced by the air resistance. When these forces are balanced it has reached terminal velocity

1st Law: A body at rest will remain at rest and a body in motion will continue at a constant velocity unless acted upon by an external force.2nd Law: Force is equal to the rate of change in momentum (F = m a is a special case)3rd Law: Action and reaction are equal and opposite

Topic 2: Momentum & Newton’s Laws

Momentum (ρ) = mass (m) x velocity (v)

Force = rate of change in momentumF = m x v / t

F = m a (When mass of the system is constant)

For the fan and the air, the action and reaction forces are equal:F1 = F2

Power: is the rate of doing work:

P = W / t or P = E / t

P = power (watts)W = work done (joules)E = energy (joules)t = time (sec)

A motor will do work by lifting a mass through a specific distance (m.g.h). Knowing how long this will take allows the power to be calculated.

Electric current is the rate of flow of charge:

I = ΔQ / Δt

I = current (amps, A)Q = charge (coulombs, C)t = time (seconds, s)

The Volt is defined as a joule per coulomb:

V = W / Q

V = potential difference (volts, V)W = work done (joules, J)Q = charge (coulombs, C)

Topic 3: Current and voltage

3232video videovideo www www photo page:www photo photo31 32

R = V / I

Ohm’s Law is a special case where V I (Provided the temperature is constant)

R = resistance (ohms, Ω)V = potential difference (volt, V)I = current (amp, A)

It is usually easier to read a digital meter to a higher level of precision and without parallax.

ICT / dataloggers allow readings of the same precision but many more of them.

Topic 3: Ohm’s Law

3333video videovideo www www photo page:www photo photo33

The current is the same everywhere in a series circuit:

In a parallel circuit, the potential difference across all the resistors is the same but the current is split in the ratio of the resistance.

Topic 3: Resistors in series and parallel

Kirchoff’s rules:

3434video videovideo www www photo page:www photo photo34 35 36

Junction Rule (Charge conservation)

At each junction, charge is conserved, so the charge entering the junction equals the charge leaving.

Loop Rule (Energy conservation)

The net charge, or potential difference, for any closed path around a circuit will be zero.

Filament lamp

As V goes up, I goes up but it is not directly proportional. The line curves because the resistance is increasing with increasing heat.

Diode

Once a threshold voltage is reached, as V goes up, I goes up in proportion.Current only flows in one direction.

Fixed resistor

It is a straight line graph. I and V are directly

proportional.

Topic 3: Current vs potential difference graphs

3535video videovideo www www photo page:www photo photo38

Electrical power:

P = I V

P = electrical power (watts, W)I = current (amps, A)V = potential difference (volts, V)R = resistance (ohms, Ω)

Energy = power x time:

W = P tW = I V t

W = Electrical work done (joules, J)

Also:

V = I RI = V / R

Therefore, substituting, electric power can also be found from:

P = I2 RP = V2 / R

If you know the electrical energy put into a motor (I V t) and the potential energy gained (m g h), then it is possible to calculate the efficiency:

R = ρ l / A

R = resistance (ohms, Ω)ρ = resistivity (ohm metre, Ω m)l = length (metre, m)A = area (meter2, m2)

ρ = R A / l

Topic 3: Core practical 2

ρ is constant for a particular material

Experiment with a tank of salt water, plate (Al foil) at each end and piece of metal moving back and forth along the tank

3737video videovideo www www photo page:www photo photo39 40

Determine the electrical resistivity of a material

Topic 3: Potential divider

The potential difference is the drop in voltage from one side of a component to the other. Think of it as a waterfall; water finally has to drop to river level but it can do so in a number of steps:

R2

R1 V1

V2

Vtot

If you know the current in the circuit and Vtot, then you can find V1, V2 etc. using V = I R

For the same value of Vtot, if the value of R1 is increased, the proportion of the potential ‘dropped’ across V1 will also increase – the V1

reading will go up.

Replacing fixed resistors such as R1 with thermistors or Light Dependent Resistors will change the values for R1

and hence R2, V1 and V2. with changing temperature or light intensity.

A

A rheostat and potentiometer can be used as potential dividers.

3838video videovideo www www photo page:www photo photo43 44

A B

Assuming that the wire is of uniform resistance, as the voltmeter moves further from A towards B, the potential drop that is measured increases.

Topic 3: Current carrying wires

I = n q v A

The amount of current flowing is defined by the density of charge carriers in the conductor, and this will change from material to material, the charge each one carries and their mean drift velocity:

3939video videovideo www www photo page:www photo photo41

Topic 3: Core practical 3

EMF (Electro Motive Force) of a power supply is the energy given to each coulomb of charge passing through it. In other words: Joules / Coulomb (Definition of the Volt)

Some of the energy given to these charges is lost in the Internal resistance of the power supply itself. The terminal potential, what’s left, is only equal to the EMF when the current is zero.

A car battery will have a very low internal resistance whilst an EHT supply will have a very high oneTerminal

potential

EMF

rR

The terminal potential is less than the EMF, unless no current flows, and the current supplied is the EMF / total resistance (R+r)

4040video videovideo www www photo page:www photo photo45 46

Determine the e.m.f. and internal resistance of an electrical cell.

Electrons (negative charges) collide with the (positive) ions in the metal lattice. Electrical Energy (Kinetic Energy) is transferred to Thermal (Heat) Energy.

Increasing the P.D. or increasing the temperature causes more energy transfer, to the ions in the lattice. More collisions occur reducing drift velocity BUT, for a semiconductor, more charge carriers (n) are released.

Metal ions / atoms

Electrons(negative charges)

Metal lattice

Topic 3: Resistance and temperature

Increasing the number of charge carriers reduces the resistance and, as temperature increases, the increased lattice vibrations cause an ntc (negative temperature coefficient) thermistor to do just this. The opposite of a filament lamp (see shape to right).
