5. The sum of potential and kinetic energy keeps changing for any system
6. Roller coaster ride is an example of transformation of energy between potential and kinetic energy
7. Electrical energy can be considered as a type of kinetic energy
8. Power and energy means the same


please tell me fast ​

Answer 1

Answer:

1. True

2. False - If a car and a motorcycle are running at the same speed, then both will have different kinetic energy. Explanation: The car will have more kinetic energy because the car has more mass than a motorcycle.

3. True

4. False - Energy can't easily be created. The law of Conservation states that the energy can neither be created nor destroyed - only converted from one form of energy to another.

5. False - The sum of P.E and K.E is equal to T.E or total energy which remains constant.

6. True

7. True

8. False - Power and energy don't mean the same way - Though there are resembles but they are different in one way or another.
