Kinetic Energy and Potential Energy
Topic 3 Lesson 2

52
Kinetic Energy
the amount of energy an object has due to its motion
An objects kinetic energy is affected by an objects mass and speed.
The faster an object moves the more kinetic energy the object has.
Kinetic energy also increases as mass increases.
53
Multiple Select
Check the boxes that are characteristics of kinetic energy.
energy that results from position or shape of an object
energy that an object possesses by being in motion
increase in speed = increase in kinetic energy
increase in mass = increase in kinetic energy
54
Multiple Choice
As mass decreases, kinetic energy increases.
true
false
55
Multiple Choice
The faster an object moves, the more kinetic energy it has.
true
false
56
Examples of Kinetic Energy
a boulder rolling down a hill
a moving car
an airplane in flight
a basketball falling through a net
Riding a bike
landslide of rocks and dirt moving down a hill
roller coaster going up the tracks
57
Multiple Select
Check the boxes that are examples of kinetic energy being displayed.
a moving car
a glass falling on the floor
ball rolling down a hill
a book sitting on top of a desk
58
Multiple Choice
At what position does the rock have the greatest kinetic energy?
A
B
C
E
59
Potential Energy
Is energy that is stored and waiting to be transferred.
It is the energy that an object has based on its height, position, or shape.
The higher the object, the greater the potential energy.
60
Multiple Select
Check the boxes that are characteristics of potential energy.
The higher the object, the greater the potential energy
The lower the object, the greater the potential energy.
Is energy that is stored and waiting to be transferred.
It is the energy that an object has based on its height and position.
61
Examples of potential energy
standing on top of a diving board
a stick of dynamite
a stretched spring or rubber band
62
Multiple Choice
Which one of the following is NOT an example of potential energy?
diving into a pool
standing on top of a diving board
a stretched spring or rubber band
stick of dynamite
63
Multiple Choice
Look at the four vehicles.
The vehicles are all moving at the same speed along a road. Which of these statements is correct?
Choose the correct answer.
The motorcycle has the most kinetic energy because it is the vehicle with the least mass.
All the vehicles have the same kinetic energy because they are all moving at the same speed.
The delivery truck has the greatest kinetic energy because its mass is greater than that of the other vehicles.
The delivery truck has the greatest kinetic energy because it has the most tires in contact with the pavement.
64
