Acceleration is the rate of change of velocity with respect to time*.
The unit of acceleration is the metre per second squared (m s-2, or m/s2 ).
Equations of Motion*
When an object (with initial velocity u) moves in a straight line with constant acceleration a, its displacement s from its starting point, and its final velocity v, change with time t.
Note that both v and u are instantaneous velocities.
The following equations tell us how these quantities are related:
v = final velocity u = initial velocity a = acceleration s= displacement (not distance) t = time
Procedure for solving problems using equations of motion.
1. Write down v, u, a, s and t underneath each other on the left hand side of the page, filling in the quantities you know, and put a question mark beside the quantity you are looking for.
2. Write down the three equations of motion every time.
3. Decide which of the three equations has only one unknown in it.
4. Substitute in the known values in to this equation and solve to find the unknown.
