Linear motion

Displacement - This is when a body undergos a change just position A1 to A2

A2-A1 = A

Speed- the rate of change in distances. The average speed is given by total distance/ time taken

Velocity- This is the rate for change of Displacement

Acceleration- the rate of change / Velocity

a= v - u/ r

v= u² + 2as

s= ut+1/2at
