Kinetic Energy #2

Front

What two factors affect an object's kinetic energy?

Back

Mass and speed.

Front

If moving at the same speed, increasing an object's mass will increase its kinetic energy. True or False?

Back

True.

Front

What is the unit used to measure energy?

Back

Joule (J).

Front

At which position(s) does the pendulum have the greatest kinetic energy?

Back

Position 3.

Front

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

Back

More.

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

It quadruples.

Front

Is kinetic energy a scalar or vector quantity?

Back

Scalar quantity.

Front

What is the relationship between kinetic energy and mass?

Back

Kinetic energy increases with an increase in mass.

Front

What is the relationship between kinetic energy and speed?

Back

Kinetic energy increases with the square of the speed.
