A student hit a high fly ball over second base in a championship softball game. As the ball rises in the air, it is acted on by the force of gravity. This force causes the ball to —

slow down, change direction, and then speed up until it falls to the ground

speed up, keep its same direction, and then slow down as it falls to the ground

travel at the same speed until it hits the ground

travel in the same direction until it hits the ground

Students placed a steel ball at the top of a long piece of tubing track. As the ball rolled down the track, the students measured the distance the ball had traveled at various times.

Gravity is the greatest unbalanced force, and it is causing the ball to speed up.

Friction with the track is the greatest unbalanced force, and it is causing the ball to slow down.

Friction with the air is the greatest unbalanced force, and it is causing the ball to slow down.

The initial push of the ball is the greatest unbalanced force, and it is causing the ball to

The two forces acting on the box are equal.

The forces on the box are acting in opposite directions.

The two forces acting on the box are unequal.

The box will move in the direction of the greater force.

The diagram represents two students pushing and pulling an object in the same direction. Which statement best describes the result of the forces?

During field day, a student recorded the motion data of a runner. The student recorded the distance traveled every 10 seconds and represented the data in a graph. What is a valid conclusion that the student can make about the runner’s motion?

The average speed of the runner remained constant as the runner covered more distance.

The average speed of the runner increased as the runner covered more distance.

The average speed of the runner decreased as the runner covered more distance.

Two students performed an investigation about distance, time, and speed. Each student recorded the data of different runners. After gathering data, the students combined the data on the graph below. Based on the information above, what is a valid conclusion that the students can make about the runners’ motion?

Runner A begins at 0 m and travels at a constant speed before stopping and staying in place at 10 m. Runner B begins at 10 m and remains still for 15 seconds before maintaining a constant speed for 30 seconds.

Runner B begins at 0 m and travels at a constant speed before stopping and staying in place at 10 m. Runner A begins at 10 m and remains still for 15 seconds before maintaining a constant speed for 30 seconds.

Runner A begins at 10 m and turns around before remaining at rest for the entire 60 seconds. Runner B begins at 0 m and travels at a constant speed before remaining at rest for 30 seconds.

Runner A begins at 10 m and remains there the entire 60 seconds. Runner B begins at 0 m and then maintains constant speed to 10 m where the runner changes speed and maintains that speed until 30 m where the runner turns around.

The graph below shows the motion of a car. Which statement below best describes the motion of the car?

The car travels at a constant speed for two minutes, increases its speed over two minutes, and then travels at a constant speed for two more minutes.

The car is stopped for two minutes, travels at a constant speed for two minutes, and then stops.

The car is stopped for two minutes, increases its speed over two minutes, and then stops.

The car increases its speed for two minutes, travels at a constant speed for two minutes, and then increases its speed over the next two minutes.

A child drove a remote control car on a tile floor for a distance of 1.6 m. The graph represents the motion of the car. Which description of motion is best represented by this graph?

The speed of the car is constant.

The speed of the car is decreasing.

The speed of the car is increasing.

Which statement best explains how a ramp makes it easier to move a heavy object over a certain distance?

It decreases the amount of force by increasing the distance.

It decreases the amount of force by decreasing the distance.

It decreases the mass of the object.

It increases the mass of the object.

A student wants to safely be able to move a cart up a ramp and onto a truck. To see which ramp would be most beneficial, the student investigates to see how the length of the ramp changes the amount of force needed to move the cart (measured in Newtons, N). Which of the following conclusions can the student make from the investigation about how to safely move the cart?

As the length of the ramp increases, the amount of force needed decreases.

As the height of the ramp increases, the amount of force needed increases.

As the length of the ramp increases, the amount of force needed increases.

As the height of the ramp increases, the amount of force needed decreases.

A student is helping his neighbor move a new dishwasher into their house. The house has three steps on the front porch that cause the porch to be 2 meters above the ground. Which method requires the least amount of force to get the dishwasher from the ground to the porch?

Place an inclined plane that is 10 meters long over the stairs, and roll the dishwasher up the inclined plane with a partner.

Lift the dishwasher up one step at a time with a partner, and rest one minute between steps.

Place an inclined plane that is 5 meters long over the stairs, and roll the dishwasher up the inclined plane with a partner.

Use a fixed pulley attached to the roof of the porch to lift the dishwasher with a partner.
