Potential

10

Gravitational Potential Energy depends on the object's what?

mass and height above the ground.

20

______, _______ items have more Gravitational Potential Energy.

Heavier, Higher.

30

If I jumped off the high dive, potential or kinetic?

Kinetic.

500

What is a good equation for The LOC&E (Law Of Conservation & Energy)?

A. E=mc^2

B. Energy In = Energy out

C. Energy In = Power In

D. Kinetic Energy = Potential Energy

B

Kinetic

10

Increasing the mass of an object does what to the kinetic energy?

Increases.

20

Two books, one is heavier and one is lighter. They are on the same shelf. If they fall, which will hit the ground first.

The heaviest. 

30

Ball A has a mass of 15 grams.  Ball B has a mass of 45 grams.  Which ball will have the most kinetic energy? They are equal in height.

Ball B is heavier, therefore it has more kinetic energy.

500

Since Kinetic Energy is moving lower than Potential, if Point A is the rock at the bottom of the hill, Point B is going up the hill, Point C is at the top of the hill, Point D is halfway from the gully from the hill, Point E is about to hit the ground, then what is the right one with the greatest kinetic energy. (EXPLAINED)

Point E is the right one because Point A is not moving which means it is POTENTIAL. Point E is Kinetic as it is moving (falling).

Random

10

The energy going __ is the same as energy going ___.

IN and OUT.

20

If flashlights heat up, then what is the TRANSFORMATION through the cycle? (Battey powered)

Chemical Energy (Battery) – Electric Energy – Electromagnetic Energy (Light) – Thermal Energy.

30

If the two balls are equal in height then ____________. (equal mass)

they are the same.

500

If the two balls have the same mass and height,

they are equal.
