Speed, Velocity And Forces

Question 1

What is the formula for speed?

Answer 1

Distance travelled / Time taken

Question 2

What is the formula for acceleration/deceleration?

Answer 2

Change is speed / time taken

Question 3

If a line on a velocity time graph is going up, what is this an example of?

Answer 3

Constant acceleration

Question 4

If the line on a velocity time graph is at a 180* angle, what is this an example of?

Answer 4

Constant speed

Question 5

If the line on a velocity time graph is going down, what is this an example of?

Answer 5

Constant deceleration

Question 6

If two forces are competing against each other, and one side is winning, which side will the direction of the force go?

Answer 6

To the winning side

Question 7

If there are two forces competing against each other and the starting direction is left (for example) but then both forces are suddenly balanced what direction (if any) will the force be travelling?

Answer 7

In the same direction but just at a constant speed with NO acceleration

Question 8

What are the four types of forces within a driving car?

Answer 8

Gravity - Downwards
Upthrust - Upwards
Friction - Backwards
Engine - Forwards
