A 100
Units of force in physics
A 100
What are Newtons?
A 200
A force that will work against
motion in everysituation is :
What is friction?
A 200
A 300
During a tug-of-warcompetition, neither
teamis able to gain an advantage this is
because the forces are _____________
What is balanced?
A 300
A 400
This is the amount of force needed to hold the
1kg object pictured.
What is 5.1 N?
[the spring scale reads 5.1,
Spring scales measure force]
A 400
Forces work in equal but opposite:
_______________
A 500
What are pairs?
A 500
B 100
These types of energy are produced by a light bulb.
What is light and
thermal energy?
B 100
[Light bulbs light up and get hot]
B 200
If an object is falling, the acceleration is due to
___________
What is gravity?
B 200
B 300
This type of energy transformation occurs
if a rock sitting on a ledge begins to fall toward the ground.
What is potential energy to kinetic energy?
B 300
B 400
This is the law that states that energy can neither be gained or
lost, only change form.
B 400
What is the Law of
Conservation of Energy?
B 500
Both of these diagrams show this type of energy
transformation.
B 500
What is chemical energy to mechanical
energy?
[both use chemical fuel for movement]
C 100
This piece of science equipment is used to find
the mass of an object.
What is a triple beam balance?
C 100
C 200
This piece of science equipment is used to find the weight or force of an
object.
What is a spring scale?
C 200
C 300
This is the acceleration due to gravity in Earth
C 300
What is 9.8 m/s2
DAILY DOUBLE
C 400
DAILY DOUBLE
Place A Wager
C 400
Estimate the weight in Newtons of a 50 kg
person.
C 400
What is about 500 N?
Using Newton’s 2nd Law formula: F=maWeight= mass x acceleration due to gravity
Weight = 50 kg x 9.8 m/s/sWeight = 50kg x 10m/s/s
Weight = 500 N
C 500
Gyrocopter
This is calculated by measuring the distance
traveled and dividing by the amount of time that is needed
to travel that distance
C 500
What is average speed?
D 100
The Law of Force and Acceleration is recognized by this
formula.
D 100
What is F=ma?
D 200
According to Newton’s 3rd Law of
Motion, forces act in equal but
___________ pairs.
What is opposite?
D 200
D 300
This Law of Motion shows the
relationship between mass and force.
D 300
What is the Law of Force and
Acceleration?
D 400
A person in a head-on car collision who is not wearing a seat belt continues to move
forward at the original speed of the car because of
______________
What is inertia?
D 400
D 500
Newton’s Law of Inertia says “objects in motion stay in motion
unless acted on by an outside force.”
Objects in the back seat of a car would move this
direction if the car suddenly stopped.
What is forward?
D 500
E 100
.This Law of Motion best explains why you may lean sideways in a car if the driver turns a corner too quickly.
What is the Law of Interia?
[Newton’s 1st Law]
E 100
E 200
A rocket is traveling in space at 10,000 m/s.
If no outside force is applied to it,
this will happen to its speed over the course of the trip.
What is stay the same?
[or stay constant]
E 200
E 300
The air friction acting on a baseball causes it to
curve as it is pitched to the catcher. This is an example of Newton’s
Law of ________________
What is inertia?
E 300
[Objects in motion remain in motion unless acted on by an outside force.
Here, the outside force is gravity causing the ball to curve down.]
E 400
You are riding in a car that has a coffee cup sitting on the dashboard.
The vehicle makes a sudden stop to avoid hitting the car
that has stopped in front of it.
This would happen to the coffee cup.
E 400
What is move forward
[until it hit the windshield]
E 500
Jumping on a skateboard and watching the
skateboard move away from you is an example of
this Law of Motion
What is Action-Reaction?
E 500
F 100
The two forces in a force pair are the
____________ force and the _____________
force.
F 100
What are action and reaction?
F 200
This is the point on the roller coaster above with the greatest gravitational
potential energy.
F 200
What is point Y?
[the highest point on the roller coaster has the greatest
gravitational potential energy]
F 300
Balanced or Unbalanced Force
Tectonic Plate Movement(Earthquake)
What is an unbalanced force?
[Unbalanced forcescause movement]
F 300
F 400
This law of motion explains why when you jump
upward, you slow down and eventually fall back to
Earth.
F 400
What is the Law of Force and Acceleration?
[acceleration due to gravity causes you to fall back to Earth. This is also known
as your weight.]
When two continental plates collide, a mountain chain is created between them.This law of motion would BEST describe
why the mountain chain is created.
F 500
What isAction-Reaction
[Action: plates pushing against each other
Reaction: land moves upward]

A roller coaster isaccelerating at 10 m/s before it comes to an
abrupt stop at the end of the ride. The mass of one cart is 300 kg.
How much force was exerted on the roller coaster to bring it to a stop?
What is 3,000 N?
Click on screen to continue
F=mass x accelerationF= 300 kg x 10 m/s
F= 3000 N
