B. Kinetic energy
C. Mechanical energy
D. Electrical energy - Answer - A. Energy transformation
I put a Pop-Tart in the toaster. Electrical energy is transformed to thermal energy to make my Pop-Tart
hot. Based on the Law of Conservation of Energy, once my Pop-Tart starts to cool, is energy lost?:
A. Yes. All the energy was used in the conversion of energy.
B. No. Energy cannot be created or destroyed.
C. Yes. The Pop-Tart is no longer hot.
D. No. Energy can be created, but it cannot be destroyed - Answer - B. No. Energy cannot be created or
destroyed.
, At a constant velocity, a 5kg bag of cement is pulled straight up a 7m wall. How much work is done by

A fish swims through the water by using its fins to push water backwards. Pushing water backwards
propels the fish forward through the water. This most nearly fits which of Newton's Laws?:
A. Newton's First Law: Force=mass(acceleration)
B. Newton's Second Law: objects in motion will stay in motion unless acted upon by a force, objects at
rest will stay at rest unless acted upon by a force
