The graph below shows the position of a moving object from 0 to 5 seconds.

According to the above information and graph, which of the following statements is true for the moving object?

• A.The moving object is accelerating and changing its speed throughout the measurement.

• The moving object is traveling at a constant speed throughout the measurement.

• The moving object is slowing down and finally stops at the 5 second mark.

• The distance the moving object travels is the same for each second.

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

The model shows the forces applied when two students push on a box.

Which statement does the model NOT accurately represent?

• 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 two forces acting on the box are equal.

The diagram represents two students pushing and pulling an object in the same direction.

Which statement best describes the result of the forces?

• The object will not move because the forces are not the same.

• The object will move in the direction of the combined forces.

• The lesser force applied is not enough to move the object.

• The combined forces on the object cancels each other out.
