Velocity and acceleration
- if object changes direction it changes velocity
- even if speed stays the same
- even if speed stays the same
- If velocity changes we can say it accelerates or decelerates
- acceleration(m/s/s)=final velocity-initial velocity / time taken for change
- if the value calculated is negative, the object is declerating
- a=v-u / t
- if the value calculated is negative, the object is declerating
