Kinetic Energy
Potential Energy
Which has more kinetic energy?
Which has more potential energy?
100
Kinetic energy is the energy of ______________
movement/motion
100
Potential energy is otherwise known as ____________ energy
stored/waiting
100
Which has more kinetic energy: a baseball or a basketball? (going the same speed)
Basketball -- more mass
100
Does the blue or yellow skiier have more potential energy?
Blue -- higher up
200
As the mass increases, kinetic energy _____________
increases
200
The potential energy of an object depends on the ________________ that it is in
position/height
200
A cheetah or a lion going at full speed? (same mass)
the cheetah has more velocity, so it has more energy!
200
A
300
If you want more kinetic energy, what should you do to the velocity of an object?
increase it
300
When the potential energy of an object decreases because it starts moving, what happens to it/where does it go?
It gets converted into kinetic energy!
300
Whose tennis ball has the most kinetic energy?
James
300
B
400
Why do kinetic energy and velocity have the relationship they have?
KE is the energy of movement. Velocity is how fast something is moving. So, if something is moving faster, it will have more kinetic energy.
400
Where on a rollercoaster would the potential energy be the highest?
on the top of the highest hill
400
Which car has the most kinetic energy?
the second
400
2 friends, Atabong and JD, are standing on a hill. Who has more potential energy?
Atabong -- he is taller
500
Why do kinetic energy and mass have the relationship they have?
because it takes more effort to push something, so therefore you are putting more energy into the object itself
500
What is an example of where the potential energy will be increasing and kinetic energy will be decreasing on a roller coaster?
traveling up a hill
starting to go around a loop
500
Object C! between A and B, we don't know because we don't know the masses of the object. Potential energy depends on the position, the height, AND the mass
600
Why does potential energy increase with increasing height?
When something is further off the ground, it has more distance to fall and therefore gravity will have a greater impact on it.
600
Which point will have the most and the least potential energy?
Most: D
Least: B
