Science Kinetic Energy Flashcards
What is kinetic energy?
Kinetic energy is the energy of an object due to its motion.
What does the kinetic energy of an object depend on?
The kinetic energy of an object depends partly on its mass.
Which ball has more kinetic energy: a bowling ball or a pinball traveling at the same speed?
The bowling ball has more kinetic energy than the pinball.
Why does the bowling ball have more kinetic energy than the pinball?
The bowling ball has more mass than the pinball.
What can be observed about the force needed to stop a bowling ball compared to a pinball?
More force is needed to stop the rolling bowling ball than the pinball.
What happens to kinetic energy when two balls with different masses move at the same speed?
They have different amounts of kinetic energy.
How might different speeds affect kinetic energy?
Different speeds could affect the amount of kinetic energy an object has.
