Question 1
There is a bowling ball rolling towards a collection of standing pins waiting to be knocked over. This is an example of what kind(s) of energy?
- potential energy
- kinetic energy
- potential and kinetic energy
- thermal energy
Explanation: Kinetic energy is the energy associated with objects in motion. Potential energy is the type of energy associated with an object's potential to do work. Thus, he answer is both potential and kinetic energy because the ball is moving forward with kinetic energy and the pins are waiting to be knocked over with potential energy.
Thermal energy (also called heat energy) is produced when a rise in temperature causes atoms and molecules to move faster and collide with each other. This question does not mention anything about temperature or heat, so this is not the correct answer.
