"Energy" is a word that's used a lot. Here, you'll learn about how it's one of the most useful concepts in physics. Along the way, we'll talk about work, kinetic energy, potential energy, and conservation of energy.
Physics is built on top of maths and requires a good understanding of it. Let's refresh our fundamental math concepts that will be used often in our physics course.
Certain ideas in physics require the prior knowledge of differentiation. The big idea of differential calculus is the concept of the derivative, which essentially gives us the rate of change of a quantity like displacement or velocity.
Certain ideas in physics require the prior knowledge of integration. The big idea of integral calculus is the calculation of the area under a curve using integrals. Let's do a fundamental course of integration.
Let's explore the ideas of displacement, velocity, and acceleration. We'll do exciting things like throw things off cliffs (far safer on paper than in real life) and see how high a ball will fly in the air.
