2: Kinematics

Question 1

Define displacement

Answer 1

Displacement is the distance from a fixed point in a specific direction

Question 2

Define velocity

Answer 2

Velocity is the rate of change of displacement

Question 3

Define acceleration

Answer 3

Acceleration is the rate of change of velocity

Question 4

List the three kinematic equations and state the assumption

Answer 4

Assume acceleration remains constant
1. s = ut + (1/2)at^2
2. v = u + at
3. v^2 = u^2 + 2as
