GCSE Physics Unit 2: Distance, Speed, and Acceleration

Explain how motion is described using distance-time graphs and velocity-time graphs.

• Motion is described by the slope of the graph.

• Motion is described by the area under the graph.

• Motion is described by the shape of the graph.

• Motion is described by the intercept of the graph.

Calculate the speed if the distance moved is 100 meters and the time taken is 20 seconds.

(Speed = distance/time)

• 5 m/s

• 10 m/s

• 15 m/s

• 20 m/s

What factors affect the total stopping distance of a car?

• Thinking distance

• Breaking distance

• Thinking and Breaking distance

• Breaking distance minus reaction time

Describe the relationship between acceleration and the gradient of a velocity-time graph.

• Acceleration is the gradient of a velocity-time graph.

• Acceleration is the area under a velocity-time graph.

• Acceleration is the inverse of the gradient of a velocity-time graph.

• Acceleration is unrelated to the gradient of a velocity-time graph.

What is the effect of increasing speed on the stopping distance of a vehicle?

• Stopping distance remains the same

• Stopping distance is unaffected by speed

• Stopping distance decreases

• Stopping distance increases

How is uniform acceleration represented on a velocity-time graph?

• As a straight line with a positive slope

• As a vertical line

• As a horizontal line

• As a curved line

If a car travels 15 meters in 30 seconds, what is its average speed?

(Speed = distance/time)

• 0.5 m/s

• 3 m/s

• 5 m/s

• 7 m/s

What is the relationship between velocity and the slope of a distance-time graph?

• Velocity is the inverse of the slope of a distance-time graph.

• Velocity is unrelated to the slope of a distance-time graph.

• Velocity is the area under a distance-time graph.

• Velocity is the slope of a distance-time graph.

How does an increase in mass affect the acceleration of an object, assuming force is constant?

• Acceleration increases

• Acceleration becomes zero

• Acceleration decreases

• Acceleration remains the same

If a cyclist covers 50 meters in 10 seconds, what is their average speed?

(Speed = distance/time)

• 2 m/s

• 15 m/s

• 10 m/s

• 5 m/s
