Energy is ued to change the motion of a golf club by applying force.

Work is not completed when

Work is done when an object is simply held.

Energy transfered J= Time (s) * Power W

100W* 30 days=

3,000J - 1,800J=

If a 500 g horse ran a 2000 m track in 120 s the average kinetic energy would be

Springs have elastic and gravitational potential energy.

The gravitational potential energy on an object is the result of

If an object is 20 N and 2 M high the GPE of the object is

Mechanical energy =

2.3J - 0.5 J=

Plants preform photosynthesis and then may be consumed by animals. Which is not an energy used in this process

If an object stops the mechanical energy stays the same

If a ball stops at the bottom of a hill the total mechanical energy is

Kinetic energy of a ball rolling down a hill transfers to thermal energy due to

When you run chemical energy transfers to

When an object starts moving kinetic energy is transferred to potential energy

When you press a piano key energy is transfered to the strings to the air to

On a roller coaster the greatest potential energy is at the bottom of the track

On a roller coaster the greatest kinetic energy is at the lowest part of the track

When riding on a roller coaster energy can be lost

Energy on a coaster moves from kinetic of a car to the track causing the track to

Energy is transformed from kinetic to potential to kinetic during a roller coaster ride.

Kinetic energy transfers to thermal energy due to friction

The total amount of energy on a roller coast
