Question

question 1 2 pts an object, like a moving roller coaster, can have both potential and kinetic energy.
true
false
question 2 2 pts nothing creates energy. if something has energy, the energy must have been transferred from something else.
true
false

Explanation:

Question 1

A moving roller coaster has kinetic energy (due to motion) and potential energy (due to height, e.g., at a hill). So it can have both.

By the law of conservation of energy, energy is neither created nor destroyed, only transferred or transformed. So energy in a system comes from transfer.

Answer:

True
