The image shows a position-time graph of four objects (P, Q, R, and S). Which statement correctly compares two objects?

• Objects P and Q move toward the starting point.

• Object Q is moving slower than object S.

• Object P is moving, and object R is stationary.

• Objects S and R both move at the same speed.

A student walks from a school building to a tree for thirty seconds. The student’s friend records the location of the student every five seconds and creates a diagram that shows those points. Between which sets of points is the student moving the fastest?

• from point 1 to point 2, and from point 2 to point 3

• from point 2 to point 3, and from point 4 to point 5

• from point 2 to point 3, and from point 5 to point 6

• from point 3 to point 4, and from point 5 to point 6

A student designs an experiment to study the effects that different materials used to make a ramp have on the motion of a toy car. In each trial, the toy car is released from rest. The image shows the design for the experiment, and the table shows the results. Trial | Material of Ramp | Speed of Toy Car at the Bottom of Ramp 1 | hard plastic | 1.6 m/min 2 | sandpaper | 1.2 m/min 3 | carpet | 0.9 m/min 4 | felt | 1.0 m/min In which trial does the toy car have the GREATEST net force at the bottom of the ramp?

• Trial 1

• Trial 2

• Trial 3

• Trial 4

The diagram shows a lab setup of a cart tied to a hook with string. A student attaches weights of different masses to the hook and observes the acceleration of the cart. Which graph correctly summarizes the expected results from the experiment?

• A graph showing acceleration increasing linearly with increasing mass of weights.

• A graph showing acceleration decreasing as the mass of weights increases.

• A graph showing acceleration remaining constant regardless of the mass of weights.

• A graph showing acceleration increasing at a decreasing rate as the mass of weights increases.

A child throws a ball up into the air and then catches the ball. The data table lists the speeds of the ball during its flight. Time in Air (seconds) | Speed (m/s) 0 | 19.6 1 | 9.8 2 | 0 3 | 9.8 4 | 19.6 How does the force of gravity affect the speed and direction of the ball during its flight?

• The force of gravity increases the speed of the ball as it falls, causing the direction of the ball to change after 4 seconds.

• The force of gravity decreases the speed of the ball as it falls, causing the direction of the ball to change after 4 seconds.

• The force of gravity increases the speed of the ball as it rises, causing the direction of the ball to change after 2 seconds.

• The force of gravity decreases the speed of the ball as it rises, causing the direction of the ball to change after 2 seconds.
