AP Physics 1 Work/Energy Review

Front

What is the principle of conservation of energy?

Back

The principle of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another. In a closed system, the total energy remains constant.

Front

Define kinetic energy and provide the formula.

Front

What is potential energy?

Back

Front

Explain the work-energy theorem.

Front

What is the formula for work done by a constant force?

Back

Front

Define power in the context of work and energy.

Front

What is the difference between elastic potential energy and gravitational potential energy?

Back

Elastic potential energy is the energy stored in elastic materials as the result of their stretching or compressing, while gravitational potential energy is the energy stored due to an object's height above the ground.

Front

How does mass affect the maximum height reached by a swinging object?

Back

For two objects swinging with the same initial speed, the mass does not affect the maximum height reached. The maximum height is determined by the initial kinetic energy, which is the same for both objects.

Front

What is the significance of negative work?

Back

Negative work occurs when the force applied to an object is in the opposite direction of its displacement. This can result in a decrease in the object's kinetic energy.

Front

Explain the concept of friction and its effect on work done.

Back

Friction is a force that opposes the relative motion of two surfaces in contact. It does negative work, which reduces the total mechanical energy of the system.
