What is the value of acceleration due to gravity at the surface of the Earth?

• 9.8 m/s²

• 10 m/s²

• 11 m/s²

• 12 m/s²

How can acceleration be calculated?

• From the gradient of a distance-time graph

• From the gradient of a velocity-time graph

• By dividing distance by time

• By multiplying mass by velocity

What is the definition of braking distance?

• The distance a vehicle travels during the driver's reaction time

• The distance a vehicle travels under the braking force

• The sum of the thinking and braking distances

• The distance a vehicle travels in free-fall

What is displacement?

• A measure of how far an object moves in a given direction

• A measure of how far an object moves without direction

• The time it takes for the brain to react to a stimulus

• The rate of change of velocity

What does a distance-time graph show?

• How an object's distance changes over time

• How an object's velocity changes over time

• How an object's acceleration changes over time

• How an object's mass changes over time

What is the typical range for human reaction times?

• 0.1-0.5 seconds

• 0.2-0.9 seconds

• 0.3-1.0 seconds

• 0.4-1.2 seconds

What are scalar quantities?

• Quantities that have both magnitude and direction

• Quantities that only have a magnitude, not a direction

• Quantities that only have a direction, not a magnitude

• Quantities that change over time

How is average speed calculated?

• By dividing the distance travelled by the time taken

• By multiplying the distance travelled by the time taken

• By dividing the velocity by the time taken

• By multiplying the velocity by the time taken

What is stopping distance?

• The distance a vehicle travels during the driver's reaction time

• The distance a vehicle travels under the braking force

• The sum of the thinking and braking distances

• The distance a vehicle travels in free-fall

What factors can affect thinking distance?

• Adverse road and weather conditions

• Tiredness, drugs, or alcohol

• The gradient of a velocity-time graph

• The mass of the vehicle
