When should you use the SUVAT equations?

The SUVAT equations are used when acceleration is constant and velocity is changing. If speed is constant, you can use the speed, distance and time triangle. They can be used to work out initial and final sp...

How to solve horizontally-launched projectile motion problems using equations of motion?

Projectile motion questions are common in A-level physics as they combine the idea of resolving vectors into their components and using the equations of motion ('suvat' equations) to calculate unknown quanti...

How to calculate temperature of expanded ideal gas.

By definition an ideal gas in a closed follows the relationship of PV=nRT, or PV/T = constant This means that Pressure * Volume/ Temperature will be the same at the start and end of the process. So P 1 V 1 /...

How does conduction work in metals?

A metal has free electrons, so when it is heated these electrons gain kinetic energy, meaning they move faster. As a result, these free electrons will collide with other electrons or ions, transferring energ...
