Answer 1

How fast you are travelling.

Question 2

In a distance time graph what does a curved line up mean?

Answer 2

An object accelerating

Question 3

In a distance time graph how do you work out how far they have travelled?

Answer 3

By the distance up and then down and add together.

Question 4

What is the formula for a acceleration?

Answer 4

A = change in velocity (v - u) / time

Question 5

What is the formula for final and initial velocity?

Answer 5

V^2 (final) - U^2 (initial) = 2 x a (acceleration) x s (distance(

Question 6

In a velocity time graph what does the gradient represent?

Answer 6

Acceleration

Question 7

How to work out how far you have travelled in a velocity time graph ?

Answer 7

Area underneath the graph.

Question 8

What does a flat, positive horizontal and negative horizontal lines represent.

Answer 8

Flat = constant velocity
Positive horizontal = acceleration
Negative horizontal = deceleration
