Science 9 Unit 1: Motion

The distance traveled by an object divided by the time it takes to travel that distance is called

• average displacement

• average acceleration

• average speed

• average activity

In order to determine speed, you must know

• time

• distance

• acceleration

• time AND distance

What is the speed of an object at rest?

• 15 km/h

• 0 km/h

• 1 km/h

• 9.8 m/s

The difference between speed and velocity is that velocity includes

• direction

• distance

• time

• weight

Which of the following does NOT indicate velocity?

• 14 m/s southeast

• 40 km/h toward Norway from Kingsford

• 80 km/h north

• 1900 km from Los Angeles to New York

Which of the following is a displacement?

• 5 m/s

• 10 ft

• -0.7 m/s²

• 3 blocks east

Acceleration is defined as the change in velocity divided by

• speed

• time

• final velocity

• distance

The S.I. unit for acceleration is

• m/s

• m/s²

• mph

• ft/s²

On a velocity-time graph, a line with a negative slope indicates that the object is

• speeding up

• slowing down

• not moving

• moving at a constant speed

If the slope of a line on a distance-time graph is positive, the object is

• moving forward at a constant speed

• speeding up

• slowing down

• not moving

• moving backwards at a constant speed
