Acceleration

Acceleration is the rate of change of velocity

Acceleration is measured in m/s/s or m/s2 or ms-2



Acceleration = Change in velocity/time taken for change

u - initial velocity

v - final velocity

s - displacement

a - acceleration

t - time

A = (v-u)/t

Acceleration is the change in velocity divided by the time it takes for the change to occur.

Like velocity, acceleration has a direction. If an object speeds up, the acceleration is in the direction that the object is moving.

If an object slows down, the acceleration is opposite to the direction that the object is moving.

Motion is not always along a straight line. If the acceleration is at an angle to the direction of motion, the object will turn. At the same time, it might speed up, slow down, or have no change in speed.



Acceleration = (Final speed - initial speed) / time
