Ch2 Review - Momentum, Velocity, and Graph Analysis

What is the momentum of a 1500 kg car moving at a velocity of 20 m/s?

• 30,000 kg·m/s

• 15,000 kg·m/s

• 75,000 kg·m/s

• 300 kg·m/s

If an object's velocity changes from 10 m/s to 50 m/s in 5 seconds, what is its acceleration?

A distance vs time graph shows a straight line with a positive slope. What does this indicate about the object's motion?

• The object is accelerating.

• The object is moving at a constant speed.

• The object is coming to a stop.

• The object is moving in reverse.

On a speed vs time graph, a horizontal line represents what type of motion?

• Acceleration

• Deceleration

• Constant speed

• Coming to a stop

What is the velocity of an object that travels 200 meters in 50 seconds?

• 4 m/s

• 10 m/s

• 250 m/s

• 100 m/s

A car increases its velocity from 0 to 60 m/s in 5 seconds. What is its acceleration?

What is the momentum of a 500 kg motorcycle traveling at 30 m/s?

• 15,000 kg·m/s

• 1,500 kg·m/s

• 50,000 kg·m/s

• 15 kg·m/s

On a distance vs time graph, a line curves upwards, getting steeper as time progresses. What does this indicate?

• The object is moving at a constant speed.

• The object is decelerating.

• The object is accelerating.

• The object is moving in reverse.

If a speed vs time graph shows a line sloping downwards towards the time axis, what does it indicate about the object's motion?

• The object has a positive accelerating.

• The object is moving at a constant speed.

• The object has a negative acceleration.

• The object is stationary.

What is the acceleration of an object if its velocity changes from 20 m/s to 40 m/s over 10 seconds?
