Accepted Answer

2.5 m/s²

Answer

3 m/s²

Answer

4 m/s²

Answer

1 m/s²

Question 11

What is the formula for calculating average speed?

Accepted Answer

Average speed = distance travelled / time taken

Answer

Average speed = distance travelled + time taken

Answer

Average speed = time taken / distance travelled

Answer

Average speed = distance travelled - time taken

Question 12

Accepted Answer

50 kilometers per hour

Answer

45 kilometers per hour

Answer

60 kilometers per hour

Answer

55 kilometers per hour

Question 13

What does uniform acceleration mean?

Accepted Answer

Acceleration that occurs at a constant rate

Answer

Acceleration that occurs only in one direction

Answer

Acceleration that is zero

Answer

Acceleration that varies in magnitude

Question 14

How is acceleration calculated?

Accepted Answer

Acceleration = change in velocity / time taken

Answer

Acceleration = distance / change in time

Answer

Acceleration = velocity / time taken

Answer

Acceleration = change in distance / time taken

Question 15

Which of the following represents non-uniform acceleration?

Answer

A train moving in a straight line at constant speed

Answer

A ball rolling at constant speed

Answer

An elevator moving upwards at a constant speed
