Acceleration Concepts Quiz

What does a positive acceleration indicate about an object's motion?

• The object is changing direction.

• The object is at rest.

• The object is slowing down.

• The object is speeding up.

How is acceleration calculated using initial and final velocities?

• a = (VI + VF) / T

• a = (VF - VI) / T

• a = (VF * VI) / T

• a = (VI - VF) / T

If a car accelerates from 35 km/h to 45 km/h in 0.25 hours, what is its acceleration?

• 40 km/h²

• 10 km/h²

• 50 km/h²

• 25 km/h²

What is the final velocity of a skateboarder who starts from rest and accelerates at 1.5 m/s² for 2 seconds?

• 4 m/s

• 1.5 m/s

• 3 m/s

• 2 m/s

In the skateboarder example, what is the initial velocity?

• 3 m/s

• 2 m/s

• 0 m/s

• 1.5 m/s

On a velocity vs. time graph, what does the slope represent?

• Time

• Acceleration

• Distance

• Speed

What does a flat line on a velocity vs. time graph indicate about the object's acceleration?

• The object is moving backward.

• The object has zero acceleration.

• The object is decelerating.

• The object is accelerating.

On a distance vs. time graph, what does a steeper slope indicate?

• The object is moving at a constant speed.

• The object is at rest.

• The object is speeding up.

• The object is slowing down.

What does a straight line with a positive slope on a distance vs. time graph indicate?

• The object is moving at a constant speed.

• The object is accelerating.

• The object is not moving.

• The object is decelerating.

What does a flattening line on a distance vs. time graph suggest about the object's motion?

• The object is speeding up.

• The object is moving at a constant speed.

• The object is accelerating.

• The object is slowing down.
