9.3 Constant acceleration formulae 1

Question 1

» What does s represent?

Answer 1

» Displacement

Question 2

What does u represent?

Answer 2

» Initial velocity

Question 3

What does v represent?

Answer 3

» Final velocity

Question 4

What does a represent?

Answer 4

» Acceleration

Question 5

What does t represent?

Answer 5

» Time

Question 6

How can you derive the formula which includes, a, t, u and v?

Answer 6

» Draw a velocity time graph
» Velocity = V - U ( final - initial)
» Time on the x axis
» v-u/t = a
» Therefore v = u + at

Question 7

How can you derive the formula which includes, u , s , v and t?

Answer 7

» The shaded area under the velocity time graph represents the formula?
» Area of a trapezium = a +b / 2 x h
» v + u / 2 x t = s
» vt + ut = 2s
