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.
