Kinetic Energy

Front

What is kinetic energy?

Back

Energy of motion.

Front

When do you have the maximum kinetic energy on a roller coaster?

Back

At the bottom of each hill.

Front

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

Back

More.

Front

What would have the greatest kinetic energy? A car driving down a hill, a person running down a hill, or a ball rolling down a hill?

Back

A car driving down a hill.

Front

If all objects are moving at the same speed, which would have the greatest kinetic energy? A tennis ball, a football, a notebook, or a box of 20 textbooks?

Back

A box of 20 textbooks.

Front

What is the formula for kinetic energy?

Back

KE = 1/2 mv² (where m is mass and v is velocity).

Front

How does mass affect kinetic energy?

Back

Kinetic energy increases with mass; more mass means more energy at the same speed.

Front

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

Back

Kinetic energy increases by a factor of four.

Front

What is the unit of measurement for kinetic energy?

Back

Joules (J).

Front

Can kinetic energy be converted to other forms of energy?

Back

Yes, kinetic energy can be converted to potential energy and other forms.
