Define Average Velocity.

The total displacement of the object in the total time:

Velocity (Vav) = total displacement (s) / total time (t)

Define Instantaneous Velocity.

The velocity at any one instant:

v = Δs / Δt

Where Δt is tending towards zero

v = ds / dt

velocity is the derivative of displacement with regards to time

What does the slope on a displacement-time graph represent?

velocity

What does the slope on a velocity-time graph represent?

acceleration

What does the area under a velocity-time graph represent?

displacement

What does the area under an acceleration-time graph represent?

velocity

How many equations of uniformly accelerated motion are there?

2

3

4

What is the first suvat equation, which is concerned with finding acceleration or velocity?

a = change of velocity / time taken

a = final velocity (v) - initial velocity (u) / time (t)

therefore: v = u + at
