Displacement = area under the graph s = displacement

Summary:
Average √ ❑ = ∆ s /∆ t = gradient of dist-time graph

√ ❑−u
Average a = = gradient of velo-time graph
∆t

Distance s = area under velo-time graph

Kinematics and calculus

The particle model: objects are considered to be a particle with, no size, no resistance and
no spinning
