Position, Velocity and Acceleration

Position is...

• location of object on coordinate plane.

• speed in specific direction.

• change in velocity.

• None of the options.

When an object moves, its position...

• remains the same

• changes

• can not be determined

Position of an object can be positive or zero only.

• Yes

• No

If the velocity of an object is zero, the object

• has a constant speed

• is speeding up

• is slowing down

• is at rest (not in motion)

An object that has zero acceleration is...

• slowing down

• not in motion

• moving with the same velocity

• speeding up

Position can be

• positive only

• positive, negative or zero

• negative only

• zero only

Change in position over time is

• velocity

• speed

• acceleration

• none of the above

If an object covers a distance of 15 meters every second, its velocity is

• 15m/s

• 5m/s

• 7.5m/s

• 30m/s

If the acceleration of an object is a negative value, then the object is

• not moving at all

• speeding up

• slowing down

• None of the above

The change in velocity over time is called

• speed

• position

• acceleration

• all
