An object travels 15 meters in the first second of travel, 15 m in its second second, and 15 m in the third second. Its acceleration is...

• 45m/s²
• 30m/s²
• 15m/s²
• 0m/s²

Describe the motion

• Speeding up;    Moving in negative direction
• Speeding up;   Moving in positive direction
• Slowing down;   Moving in positive direction
• Slowing down;   Moving in negative direction

Suppose you take a trip that covers 180km in 3 hours. Your average speed is...

• 30km/hr
• 360km/hr
• 180 km/hr
• 60km/hr

Does the speedometer of a car read average speed or instantaneous speed?

• average speed
• instantaneous speed

On this position-time graph, which of the objects has a bigger speed?

• A

• B

• neither, they have the same speed

What is average speed?

• distance divided by time
• total distance divided by total time
• speed divided by time
• total speed divided by time

Calculate the speed of object A.

• 2 m/s
• 0.5 m/s
• 3 m/s
• 6 m/s

Calculate the speed of object B.

• 6 m/s
• 2 m/s
• 1 m/s
• 4 m/s
