Physics Quiz: Distance Time Graphs

What is the definition of speed?

• Distance over time

• Displacement over time

• Time over distance

• Speed over distance

What is the difference between speed and velocity?

• Speed is a vector quantity, velocity is a scalar quantity

• Speed has size and direction, velocity has only size

• Speed is uniform, velocity is non-uniform

• Speed is distance over time, velocity is displacement over time

What does the horizontal part of a distance time graph indicate?

• Uniform speed

• Non-uniform speed

• Acceleration

• Not moving

How can the speed be calculated from a distance time graph?

• By finding the slope of the line

• By working out the gradient

• By calculating the y-intercept

• By looking at the area under the graph

What does the gradient of a displacement time graph represent?

• Speed

• Distance

• Velocity

• Acceleration

What is the velocity of the car with a displacement time graph showing a gradient of 0.86?

(to the nearest m/s)

• 4 meters per second

• 1 meter per second

• 2 meters per second

• 3 meters per second

How would you calculate velocity from a displacement time graph? (two answers)

• Displacement over time

• Change in x over change in y

• Distance over time

• Change in y over change in x

What does the gradient of a distance time graph represent?

• Acceleration

• Speed

• Velocity

• Displacement

What is the value of the gradient for a displacement time graph showing a displacement of 8 over a time of 4?

• 1 meter per second

• 2 meters per second

• 3 meters per second

• 4 meters per second

What is the key difference between speed and velocity?

• Speed is displacement over time, velocity is distance over time

• Speed is uniform, velocity is non-uniform

• Speed has only size, velocity has size and direction

• Speed is a scalar quantity, velocity is a vector quantity
