Speed and Acceleration GCSE Quiz

What is the formula to calculate speed?

• Speed = Distance - Time

• Speed = Distance / Time

• Speed = Time / Distance

• Speed = Distance * Time

What is the SI unit of speed?

• km/h

• kg/m

• mph

• m/s

What is the formula to calculate acceleration?

• acceleration = speed / time

• acceleration = force / mass

• acceleration = (change in velocity) / (time taken)

• acceleration = distance / time

What is the SI unit of acceleration?

• m/min

• cm/s

• m/s^2

• km/h

A car travels 200 meters in 20 seconds. What is its speed?

• 20 meters per second

• 5 meters per second

• 15 meters per second

• 10 meters per second

A car accelerates from 20 m/s to 40 m/s in 5 seconds. What is its acceleration?

• 6 m/s^2

• 2 m/s^2

• 10 m/s^2

• 4 m/s^2

What is the difference between speed and velocity?

• Acceleration

• Velocity

• Time

• Distance

Explain the concept of constant acceleration.

• Constant acceleration refers to the situation where an object's velocity changes by the same amount in each equal time period.

• Constant acceleration is when an object's velocity changes at random intervals.

• Constant acceleration means the object is at rest and not moving at all.

• Constant acceleration refers to the situation where an object's velocity remains constant over time.

What is the relationship between distance, speed, and time?

• distance = speed x time

• distance = speed - time

• distance = speed / time

• distance = speed + time

How does air resistance affect the acceleration of an object?

• It reduces the acceleration of the object.

• It has no effect on the acceleration of the object.

• It causes the object to stop accelerating.

• It increases the acceleration of the object.
