Mastering Motion and Acceleration

Motion occurs when something moves and is relative depending on what the motion is being measured against.

Acceleration is the rate at which an object changes its velocity.

The equations of motion are: $v = u + at$, $s = ut + \frac{1},{2}at^2$, $v^2 = u^2 + 2as$.

<p>To find the total velocity, you would have to add up all the velocities as vectors.</p> Signup and view all the answers

<p>Relativity tells us that no motion is absolute and that it depends on what we're measuring motion against.</p> Signup and view all the answers
