Kinematics Equations

Question 1

Speed equation

Answer 1

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

Question 2

Velocity equation

Answer 2

Velocity (m/s) = displacement (m) / time (s)

Question 3

Acceleration equation

Answer 3

Acceleration (m/s^2) = change in velocity (m/s) ÷ time (s)

Question 4

Components of velocity time graph

Answer 4

Gradient = acceleration

Area under graph= displacement

Question 5

Trapezium area

Answer 5

= 0.5(a+b)h

Question 6

Components of acceleration time graph

Answer 6

Area = velocity
Gradient = jerk

Question 7

Components of displacement time graph

Answer 7

Gradient = velocity
