How does increasing friction affect the motion of a moving object?

• It speeds up the object

• It slows down the object

• It has no effect on the object

• It changes the direction of the object

Which graph correctly represents an object that is not moving?

• A horizontal line on a distance/time graph

• A vertical line on a distance/time graph

• A diagonal line on a distance/time graph

• A curved line on a distance/time graph

Explain how a change in mass affects the motion of an object when the same force is applied.

• The object will move faster with more mass

• The object will move slower with more mass

• The object will not move at all

• The object will move at the same speed regardless of mass

A graph shows a line that slopes upwards from left to right. What does this indicate about the object's motion?

• The object is slowing down

• The object is speeding up

• The object is stopped

• The object is moving at a constant speed

A student measures the distance a toy car travels over time and creates a graph. How can the student determine if the car is accelerating?

• By checking if the graph line is horizontal

• By checking if the graph line is vertical

• By checking if the graph line is curved

• By checking if the graph line is straight

Why does a heavier object require more force to move than a lighter object?

• Because it has more friction

• Because it has more mass

• Because it has less gravity

• Because it has less speed
