Back

Law of Conservation of Energy

Front

The _____ energy is due to the position of an object.

Back

Potential

Front

If the velocity of an object goes from 2 m/s to 4 m/s, how would that change the Kinetic Energy?

Back

It will quadruple (x4)

Front

What is the gravitational potential energy of a 440 N apple 4 m high on a tree?

Back

1,760 J

Front

What is the formula for Kinetic Energy?

Back

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

Front

What is the formula for Potential Energy?

Back

PE = mgh (where m is mass, g is acceleration due to gravity, and h is height)

Front

What is the unit of energy in the International System of Units (SI)?

Back

Joule (J)

Front

What is the relationship between mass and Kinetic Energy?

Back

Kinetic Energy is directly proportional to mass.

Front

What happens to Potential Energy if the height of an object is doubled?

Back

Potential Energy also doubles.
