In this deck, we'll explore what happens when forces cause movement and change the shape of objects. You'll learn about the concept of 'work done' in physics and its direct link to energy transfer. We'll also investigate how materials like springs behave when stretched, covering Hooke's Law, and the crucial difference between elastic and inelastic deformation.

In everyday language, 'work' can mean many things, but in physics, it has a very specific meaning. Work is done whenever a force causes an object to move. For work to be done, two things must happen: a force must be applied, and the object must move a certain distance in the direction of that force. The amount of work done is calculated by multiplying the force by the distance moved. So, pushing a heavy box across a floor requires work, but pushing against a solid wall that doesn't move does no work at all, no matter how tired you get.

There's a fundamental connection between work and energy. In fact, they are two sides of the same coin. Whenever work is done, energy is transferred from one store to another. For example, when you lift a book, you do work against the force of gravity. The chemical energy from your muscles is transferred to the book as gravitational potential energy. The amount of work you do is exactly equal to the amount of energy the book gains. This principle is vital: work done equals energy transferred.
