2.1 Distance, Time and Speed
Speed = Distance moved / time taken
v = d/t
Average speed = total distance travelled / total time taken
2.2 Speed, Velocity and Acceleration
Acceleration = change in velocity / time taken
2.3 Speed- Time graphs
Area under the speed time graph gives the distance moved.
2.4 Acceleration of free fall
Acceleration due to free fall (acceleration due to gravity) does not depend on the material, size or shape.
