AP Physics: Work and Energy

Front

What is energy stored in a gravitational field?

Back

Gravitational potential energy.

Front

At which point does an object have the most gravitational potential energy when released from rest?

Back

At point A and G.

Front

If Jill does twice the work in half the time compared to Jack, how does her power output compare?

Back

Jill's power output is four times Jack's power output.

Front

What is the formula for elastic potential energy?

Back

=1/2kx².

Front

What is the average power required to accelerate a 2000 kg car from 30 m/s to 60 m/s in 9 seconds?

Back

300,000 watts.

Front

Define work in the context of physics.

Back

Work is done when a force causes displacement of an object, calculated as Work = Force x Distance.

Front

What is the formula for kinetic energy?

Back

Kinetic energy = 1/2 mv².

Front

What is the relationship between work and energy?

Back

Work done on an object results in a change in its energy.

Front

What is the principle of conservation of energy?

Back

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

Front

What is power in physics?

Back

Power is the rate at which work is done or energy is transferred, calculated as Power = Work / Time.
