Kinetic Energy

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion.

Front

Which of the following would NOT increase an object's kinetic energy?

Back

Decreasing the object's mass.

Front

A change in an object's speed has a(n) _______ effect on its kinetic energy than a change in its mass.

Back

greater

Front

Energy and work are measured in:

Back

joules.

Front

If two objects have the same kinetic energy but different masses, what can you conclude about their speeds?

Back

The object with less mass has a higher speed.

Front

What is the formula for calculating kinetic energy?

Back

Kinetic Energy (KE) = 1/2 * mass (m) * speed (v)^2.

Front

What happens to kinetic energy if the speed of an object doubles?

Back

The kinetic energy increases by a factor of four.

Front

What is the relationship between mass and kinetic energy?

Back

Kinetic energy is directly proportional to the mass of the object.

Front

How does height affect kinetic energy?

Back

Height does not directly affect kinetic energy; it affects potential energy.

Front

What is the unit of measurement for kinetic energy?

Back

Joules (J).
