The graph represents the relationship between distance and time for an object moving in a straight line. According to the graph, the object is

• Motionless

• Moving at constant speed

• accelerating

• decelerating

A runner changing speed from 3 m/s to 5 m/s is an example of

• Acceleration

• Changing direction

• Velocity

• Constant Speed

Which statement about the movement of an object with zero acceleration is true?

• The object must be at rest

• The object must be slowing down

• The object may be speeding up

• The object may be in motion

As an object falls to the ground from a height, its speed

• Increases

• Decreases

• Remains the same
