1. Chapter 5: Energy
Section 1 Part 2

2. What is potential energy?
Objects receive energy when they are moved or change shape
This energy can be _____________ for later use
Potential energy (_____):
Stored energy resulting from ______________/shape
Energy with the potential to do work
stored PE
position

3. What types of potential energy exist?
Elastic
_________________ potential energy (EPE)
Some objects are elastic
Can be stretched or compressed and return to original shape
Examples: ___________________
Rubber band/spring

4. What types of potential energy exist?
When you stretch or squish an object
Your energy goes ____ the object
The object stores the energy until it is released
When it is let go the energy releases
into

5. What types of potential energy exist?
To get more EPE you would:
Stretch an object ___________
Compress an object ___________
more
more

6. What types of potential energy exist?
______________ potential energy (GPE)
When you lift an object off the ground
Your energy goes _________ the object
The object stores the energy until it is released
When it is let go the energy releases
Gravitational
into

7. What types of potential energy exist?
The amount of GPE depends on 2 things:
The _____________ an object is lifted to
The _____________ of an object (in Newtons)
height
weight

8. What types of potential energy exist?
To get more GPE you would:
_____________ height
_____________ weight
increase
increase

9. Kinetic Energy
Whether energy is kinetic or potential depends on if it is _______________ or not
moving
Potential Energy
Kinetic Energy

10. Kinetic Energy Moving objects can do ___________ on other objects
So, kinetic energy is the energy the object has due to its _____________
It comes from the Greek word __________, which means ______________
work
motion
kinetos
moving

11. Kinetic Energy There are 2 things that affect KE
KE increases as ___________ increases
Example: If a bowling ball and a golf ball were rolling at the same speed, then the ______________ would have more KE because it has __________ mass.
mass
bowling ball
more

12. Kinetic Energy There are 2 things that affect KE
KE increases as ___________ increases
Example: If two identical bowling balls were rolling, one at 5m/s and one at 1m/s, then the one rolling at _________ would have more KE because it has __________ velocity.
velocity
5m/s
more
1m/s
5m/s

13. Kinetic Energy KE can be calculated KE =____ X ________ X _______ .5
Based on the formula, changing the ________ of an object has a greater impact on KE than changing the _____. .5
Mass
(Velocity)2
Velocity
mass
1m/s
5m/s
