Acceleration and Velocity

Multiple Choice

What is the definition of speed?

• Distance/Time
• Change in velocity/Time
• A change in momentum

Multiple Choice

Which of the following best describes velocity?

• The total distance traveled over time

• The speed in a given direction

• The amount of force applied to an object

• The time taken to stop an object

Multiple Choice

Why is displacement used instead of distance when calculating velocity?

• Because velocity is a vector and requires direction, while distance does not have direction.

• Because displacement is always greater than distance.

• Because distance is a vector quantity.

• Because displacement is easier to measure.

Multiple Choice

Select the description of motion from A - B.

• Slowing down away from the origin

• Speeding up away from the origin

• Constant velocity away from the origin

• Constant velocity towards the origin

Multiple Choice

A roller coasters accelerates from an initial velocity of of 6.0 m/s to a final velocity of 70 m/s over 4 seconds.  What's the acceleration?

• 24 m/s²
• 18 m/s²
• 16 m/s²
• 16 m/s

Multiple Select

Select all the correct statements about acceleration and speed-time graphs.

• The gradient of a speed-time graph gives acceleration.

• A horizontal line on a speed-time graph means constant speed.

• The area under a speed-time graph gives distance travelled.

• A curved line on a speed-time graph always means constant acceleration.

Multiple Choice

Which of the following statements about the gradient of a distance-time graph is correct?

• The gradient gives the speed of the object.

• The gradient gives the acceleration of the object.

• The gradient gives the distance travelled by the object.

• The gradient gives the velocity only if the speed is constant.

Multiple Choice

What is the formula for calculating velocity?

• Velocity = Displacement / Time

• Velocity = Time / Displacement

• Velocity = Speed x Time

• Velocity = Distance + Time
