PS 3.3 - Mass, Speed, & Kinetic Energy

Front

What is the formula for calculating kinetic energy?

Back

KE = 0.5 x mass x (speed x speed)

Front

What happens to kinetic energy if the mass of an object increases?

Back

Increasing an object's mass will increase its kinetic energy.

Front

What is the unit of measurement for kinetic energy?

Back

Joules (J)

Front

If two objects are moving at the same speed, how does their mass affect their kinetic energy?

Back

The object with more mass will have more kinetic energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion.

Front

Which has more kinetic energy: a moving car or a stationary car?

Back

A moving car has more kinetic energy.

Front

If an object is at rest, what is its kinetic energy?

Back

The kinetic energy is 0 Joules.

Front

How does speed affect kinetic energy?

Back

Kinetic energy increases with the square of the speed.

Front

What is the relationship between mass and kinetic energy?

Back

Kinetic energy is directly proportional to mass.

Front

If a 2 kg object is moving at 3 m/s, what is its kinetic energy?

Back

KE = 0.5 x 2 kg x (3 m/s x 3 m/s) = 9 Joules.
