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?
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
