P9 - Motion

Question 1

Equation for constant speed

Answer 1

Speed(m/s) = distance travelled (m)/ time taken (s)

Question 2

State the difference between velocity and speed

Answer 2

Velocity has direction but speed doesn’t.

Question 3

Acceleration equation

Answer 3

Change in velocity = final velocity - initial velocity
acceleration (m/s²) = change in velocity (m/s) / time taken for change (s)
a = v - u / t
