 two objects with different weights are moving at the same speed, the lighter object has

• More energy than the heavier object

• No mass

• Less energy than the heavier object

• Greater speed

If speed is increased the more....

• Mrs. Romanelli will eat cupcakes

• Fun you will have

• energy it gains

• Less energy it gains

True or False, Energy is conserved because it can be destroyed.

• True

• False

 Energy is conserved because energy ( can always be increased, cannot be created or destroyed, decreases wtih heavier masses)

How can a dam make stored energy?

• It cannot store energy

• It is storing energy by wind mills that surround it.

• It holds energy from the sun shining on the water

• It holds back water from a larger river

If two objects with different weights are moving at the same speed, the heavier object has

• More energy than the lighter object

• No energy

• The same energy as the lighter object

• Less energy than the lighter object
