How potential and kinetic energies relate with friction in a skateboard park.

Here is projectile video number one looking at projectiles aimed at walls.

By working out the horizontal and vertical components then using the horizontal component to determine the time it takes to reach the wall, the displacement S can be found.

An important skill in physics is to rearrange formulas. Click the picture to watch the lesson movie.

A quick video to calculate the acceleration down a slope.
