Question 8

Define average speed.

Answer 8

Distance travelled / time taken

Question 9

Define instantaneous speed.

Answer 9

The speed an object travels at a given moment in time.

Question 10

Define acceleration.

Answer 10

The rate of change of velocity.

Question 11

Define velocity.

Answer 11

The rate of change of position.

Question 12

Define Newton’s First Law.

Answer 12

When the net force on an object is zero
