Kinetic Energy

Front

What is kinetic energy?

Back

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

Front

What is the formula for calculating kinetic energy?

Back

The formula for kinetic energy (KE) is KE = 1/2 mv², where m is mass and v is speed.

Front

What unit is used to measure energy?

Back

Energy is measured in joules.

Front

How does mass affect kinetic energy?

Back

Kinetic energy increases with an increase in mass, assuming speed remains constant.

Front

How does speed affect kinetic energy?

Back

Kinetic energy increases with the square of the speed; if speed doubles, kinetic energy increases by four times.

Front

What happens to kinetic energy when an object speeds up?

Back

Kinetic energy increases as an object speeds up.

Front

What happens to kinetic energy when an object slows down?

Back

Kinetic energy decreases as an object slows down.

Front

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

Back

The object with greater mass will have more kinetic energy.

Front

What is the relationship between kinetic energy and height?

Back

Kinetic energy is not directly affected by height; it is primarily affected by mass and speed.

Front

What would happen to kinetic energy if an object's mass is decreased?

Back

Decreasing an object's mass would decrease its kinetic energy if speed remains constant.
