Motion equations GCSE Physics

What is the average speed equation?

• average speed = total time / distance travelled

• average speed = time taken / total distance

• average speed = total distance travelled / time taken

• average speed = total distance travelled x time taken

What is the name given to a physical quantity described in both size and direction?

Which units could NOT be used for the speed of an object?

• m/s

• km/h

• s/m

• miles per hour

What physical quantity has the unit metre per second squared?

What is the equation for the acceleration of an object?

• change in velocity / time taken

• change in time / velocity

• change in time x velocity

• change in velocity x time taken

What is the standard physical unit for displacement?

What is the alternative equation for calculating the average speed of an object?

• (initial speed - final speed) / time taken

• (initial speed + final speed) / time taken

• (initial speed - final speed) / 2

• (initial speed + final speed) / 2

What is the symbol equation for acceleration?

• a = (v + u) / s

• a = (v - u) / t

• a = (u - v) / t

• a = (u - v) / s

Which of the following equation is the average speed equation re-arranged so that 'time taken' is the subject.

• time taken = average speed / distance travelled

• time taken = average speed x distance travelled

• time taken = distance travelled / average speed

• time taken = distance travelled x average speed

Which of the following equation is the acceleration equation re-arranged so that 'change in velocity' is the subject.

• change in velocity = acceleration / time taken

• change in velocity = acceleration x time taken

• change in velocity = time taken x acceleration

• change in velocity = time taken / acceleration
