P9 - Motion

Question 1

Distance Travelled, s (m) =

Answer 1

distance travelled, s (m) = speed, v (m/s) × time, t (s)
s = v × t

Question 2

average speed (m/s) =

Answer 2

average speed (m/s) = total distance travelled (m) x total time taken (s)

Question 3

The unit of acceleration is

Answer 3

The unit of acceleration is metres per second squared, m/s^2

Question 4

acceleration, a (m/s^2) =

Answer 4

acceleration, a (m/s^2) = change in velocity, Δv (m/s) / time taken (s)
a = Δv / t

Question 5

The following equation applies to objects with uniform acceleration:

Answer 5

(final velocity)^2 – (initial velocity)^2 = 2 × acceleration × distance
v^2 – u^2 = 2as

Question 6

gradient of triangle =

Answer 6

height / base
