Physics in Motion

Work and Energy

The phenoma that makes things move, and is what makes the universe run at all scales. Learn about energy conservation, conservative forces, power and potential energy.

Conservative Forces

Through the consideration of mechanical systems, we will explore the notion of energy, and what it is. Learn about conservative forces.

Energy Conservation and Work

The conservation of energy is useful for understanding the motion of a particle under their influence.

Work and Potential Energy

When the forces acting on an object are conservative, there exists a very simple relation between the work done and the potential energy.


The rate of change of work with time.
