Force, Motion, and Energy

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion. The faster an object moves, the more kinetic energy it has.

Front

Which object has the greatest kinetic energy if all are moving at the same speed: a tennis ball, a football, a notebook, or a box of 20 textbooks?

Back

A box of 20 textbooks has the greatest kinetic energy because it has more mass.

Front

What type of energy does a hand drill use to make holes in wood?

Back

A hand drill uses mechanical energy to make holes in wood.

Front

What two factors are needed to describe a car's motion?

Back

To describe a car's motion, you need to know its direction and speed.

Front

What form of energy increases the temperature of water when heated by a candle?

Back

The form of energy that increases the temperature of water is thermal (heat) energy.

Front

What happens to Dominick's speed as he walks for half an hour according to the app?

Back

Dominick's speed decreases as he walks for half an hour.

Front

What is the definition of force?

Back

Force is a push or pull on an object that can cause it to move, stop, or change direction.

Front

What is motion?

Back

Motion is the change in position of an object over time.

Front

What is energy?

Back

Energy is the ability to do work or cause change.

Front

What is the difference between potential energy and kinetic energy?

Back

Potential energy is stored energy based on an object's position, while kinetic energy is the energy of an object in motion.
