4.) At any point in the system the ME of the ball is
a. constant b. minimum c. maximum d. zero
5.) At which point the ball have a maximum potential
energy?
a. at A b. at B c. at C d. at D
II. Modified True or False. (2 pts each)
Write True if the statement is correct and if the
statement is false change the underlined word to make
the statement correct. Write your answer on the blank.
1. The object's potential energy at the highest point is
equal to its kinetic energy at the lowest
point._______
2. The sum of the object's kinetic and potential energy is
Thermal energy.______
3. Energy is conserved in a closed system if the total
mechanical energy is constant_______
4. The object's loss in PE is the gain in its KE._______
5. The Law of Conservation of energy states that the total
mechanical eneray of a closed system is conserved. No
energy is lost. Energy is only change from one form to
another form_________​
