Physics S1 Final Review

Front

What happens to an object's gravitational potential energy as it falls toward the Earth?

Back

It decreases.

Front

Which point in a falling object's trajectory has the least kinetic energy?

Back

Point A.

Front

What is the definition of power in physics?

Back

The rate at which work is done.

Front

True or False: Energy can not be created or destroyed, only converted from one form to another.

Back

True.

Front

How much work is done when a force of 5N is applied over a distance of 12 meters?

Back

60 J.

Front

Define gravitational potential energy.

Back

The energy an object possesses due to its position in a gravitational field.

Front

What is kinetic energy?

Back

The energy an object has due to its motion.

Front

State the work-energy principle.

Back

The work done on an object is equal to the change in its kinetic energy.

Front

What is the formula for calculating work?

Back

Work = Force x Distance.

Front

Explain the law of conservation of energy.

Back

Energy cannot be created or destroyed, only transformed from one form to another.
