Define acceleration

• ratio of velocity to time

• rate of change in displacement

• rate of change in velocity

• ratio of force to mass

Which graph best represents how s, the displacement of a body, varies with time?

• A

• B

• C

• D

Describing the motion of the object

• A.uniform velocity, acceleration, deceleration, stationary

• A.deceleration, uniform velocity, acceleration, stationary

• A.stationary, acceleration, deceleration, unifrom velocity

• A.acceleration, uniform velocity, deceleration, stationary

A sphere is released and falls. Its initial acceleration reduces until it eventually begins to travel at constant terminal velocity. Which displacement-time graph best represents the motion of sphere?

• A

• B

• C

• D

What is the acceleration of the object during this time?

• 4 m/s²

• 20 m/s²

• 50 m/s²

• 100 m/s²

What is the formula to calculate speed?

• S = t/d
• S = d/t
• S = d x t
• S = t x d

A change in velocity over time is known as:

• acceleration
• constant speed
• average speed
• displacement

How do you calculate average speed?

• divide total time by total distance
