5. Uniform Acceleration

Question 1

Define the term speed

Answer 1

How fast something is moving regardless of direction

Question 2

Define the term displacement

Answer 2

How far an object has travelled from its starting point in a given direction

Question 3

Define the term velocity

Answer 3

The rate of change of an object’s displacement (i.e. speed in a given direction)

Question 4

Define the term acceleration

Answer 4

The rate of change of an object’s velocity

Question 5

Give the 4 equations of uniform acceleration

Answer 5

1. v = u + at
2. s = (u + v)/2 x t
3. s = ut + 1/2 at^2
4. v^2 = u^2 + 2as
