Motion & Forces Unit Test Review

What do we call the movement of an object from one location to another over time?

• Displacement

• Motion

• Velocity

• Acceleration

A rabbit covers 80 meters in 20 seconds. What is its speed?

• 5 m/s

• 4 m/s

• 8 m/s

• 20 m/s

What makes velocity different from speed?

• It accounts for acceleration.

• It includes direction.

• It is measured in different units.

• It does not involve time.

A car moves 15 meters per second at a constant speed. What does this describe?

• A. Acceleration

• B. No acceleration

• C. Increasing velocity

• D. Slowing down

If a train travels 120 meters in 6 seconds, what is its speed?

• 15 m/s

• 12 m/s

• 20 m/s

• 10 m/s

• 45 cm

• 30 cm

• 5 cm

• 5 cm

What is the acceleration of an object moving at a constant speed without changing direction?

• Zero

• Positive

Why does a Ferris wheel accelerate even if it moves at a constant speed?

• It moves in a straight line.

• Its direction constantly changes.

• Gravity pulls it downward.

• A motor keeps it in motion.

What do we call a stationary object used to measure motion?

• Frame of reference

• Inertia point

• Speed detector

• Acceleration marker
