Free-fall:  a special case of uniformly accelerated motion
a
When you drop a hammer, it falls to the ground.  While it is falling, the only force acting on it is gravity. (There’s also a little bit of air resistance, but for a hammer moving at...

## 25 JunWhat do you need to know about Kinematics?

Defining Velocity
Velocity is the rate of change of position.
If you go in a straight line from A to B, your velocity is just the distance between A and B divided by the time it took to go from A to B.
e.g. If...
