Understanding Motion through Graphs

What is the primary purpose of using motion graphs?

• To measure the temperature of an object

• To determine the color of an object

• To calculate the mass of an object

• To describe and analyze motion

In a distance-time graph, what does a straight line indicate?

• The object is accelerating

• The object is stationary

• The object is moving at a constant speed

• The object is moving in a circle

What does the gradient of a distance-time graph represent?

• The acceleration of the object

• The speed of the object

• The mass of the object

• The direction of the object

In a speed-time graph, what does the area under the graph represent?

• The speed of the object

• The mass of the object

• The time taken

• The distance traveled

What does a horizontal line on a speed-time graph indicate?

• The object is moving at a constant speed

• The object is accelerating

• The object is decelerating

• The object is stationary

How is displacement different from distance?

• Displacement is a scalar quantity

• Displacement is always greater than distance

• Displacement is measured in kilograms

• Displacement is a vector quantity

What does a zero acceleration on an acceleration-time graph indicate?

• The object is accelerating

• The object is moving at a constant speed or is stationary

• The object is decelerating

• The object is moving in a circle

What is the relationship between velocity and speed?

• Velocity is a scalar and speed is a vector

• Velocity and speed are the same

• Velocity is always greater than speed

• Velocity is a vector and speed is a scalar

How do you add two velocities that are in the same direction?

• Add their magnitudes

• Subtract their magnitudes

• Divide their magnitudes

• Multiply their magnitudes

What does the area under a velocity-time graph represent?

• The displacement of the object

• The speed of the object

• The acceleration of the object

• The mass of the object
