Work and Energy Flashcard

Front

What is the formula for Work?

Back

Work = Force x Distance (W = F x d)

Front

What is the relationship between work and kinetic energy?

Back

Work is equal to the change in kinetic energy.

Front

What happens to the total energy in a closed system when energy is transformed?

Back

The total amount of energy stays the same.

Front

Define gravitational potential energy.

Back

Gravitational potential energy is the energy possessed by an object due to its position in a gravitational field.

Front

What type of energy does an extended spring store?

Back

An extended spring stores potential energy.

Front

What is the unit of energy?

Back

The unit of energy is Joules.

Front

What is the unit of force?

Back

The unit of force is Newtons.

Front

What is kinetic energy?

Back

Kinetic energy is the energy possessed by an object due to its motion.

Front

How is potential energy calculated for an object at height?

Back

Potential Energy (PE) = mass (m) x gravitational acceleration (g) x height (h) (PE = mgh)

Front

What is the principle of conservation of energy?

Back

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