Kinetic energy

Front

Energy due to motion is ____________ energy.

Back

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

Front

At the top of the highest point/peak on a roller coaster, how is the energy split between potential and kinetic energy?

Back

At the highest point, the energy is 100% potential energy and 0% kinetic energy.

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 velocity.

Front

A cheetah can run briefly with a speed of 31.0 m/s. Suppose a cheetah with a mass of 47.0 kg runs at this speed. What is the cheetah’s kinetic energy?

Back

The cheetah’s kinetic energy is 22,584 Joules.

Front

The faster an object moves, the ________ kinetic energy it has.

Back

The faster an object moves, the more kinetic energy it has.

Front

As mass increases, KE ...

Back

As mass increases, kinetic energy increases.

Front

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

Back

If the speed of an object doubles, its kinetic energy increases by a factor of four.

Front

What is the relationship between kinetic energy and velocity?

Back

Kinetic energy is directly proportional to the square of the velocity.

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state.

Front

How does height affect potential energy?

Back

Potential energy increases as height increases.
