Velocity is speed in a given direction
An object moving at a steady speed is accelerating if its direction is changing
Work in pairs to think of 4 situations which exemplify speed oracceleration
egAt constant speed on a round about your direction is changing soyour velocity is changing
Wet Clothes are dried when spun because their velocity changes ,they are being accelerated and experience centripetal force!
A car moving at 60 mph collides with a car moving at 30mph. Theamount of damage depends on the cars original directions.
A fair ground ride where your velocity changes and not just yourspeed is more interesting

Acceleration = change in velocity (m/s) time (s)
(m/s/s)
Acceleration is the change in velocity each second.
eg What is the acceleration of the cyclist?
Initial speed = 8 m/sfinal speed = 20 m/stime taken = 6 sec
acceln = v = 12 m/s t 6 s
= 2m/s/s
Acceleration = change in velocity (m/s) time (s)
(m/s/s)
Acceleration is the change in velocity each second.
eg What is the acceleration of the cyclist?
Initial speed = 8 m/sfinal speed = 20 m/stime taken = 6 sec
acceln = v = 12 m/s t 6 s
= 2m/s/s
Acceleration = change in velocity (m/s) time (s)
(m/s/s)

Initial speed = 8 m/sfinal speed = 20 m/stime taken = 6 sec
acceln = v = 12 m/s t 6 s
= 2m/s/s
Calculate these accelerations:
Q1. A motor bike accelerates from 10m/s to 20m/s in 2 sec.
Q2. Concorde accelerates from rest to 40m/s in 10 sec.
Q3. A wasp accelerates from 2m/s to 6m/s in 1sec.
