Answer 4

Distance/time

Question 5

Equation for acceleration?(in equation sheet)

Answer 5

(Final velocity-inital velocity)/time

Question 6

What is the acceleration of an object?

Answer 6

Change in velocity per second

Question 7

On a velocity time graph what is a steep upward line?

Answer 7

Acceleration

Question 8

On a velocity time graph what is a horizonal line?

Answer 8

Constant velocity

Question 9

Answer 9

Constant acceleration

Question 10

What is the distance travelled on a velocity time graph?

Answer 10

Area underneath the line

Question 11

Equation for distance travelled on a velocity time graph?

Answer 11

0.5( inital velocity+finaly veocity) x time

Question 12

How do you get the gradient of a sloping line in a distance time graph?

Answer 12

Get a tangent, create a triangle and do rise over run.

This will equal the speed
