A car is moving in a straight line at a constant speed. Suddenly, a strong wind starts blowing against the direction of the car's motion. What will likely happen to the car's speed?

• The car's speed will increase.

• The car's speed will decrease.

• The car's speed will remain the same.

• The car will stop immediately.

Two students are pushing a box in opposite directions with equal force. What will be the net force on the box, and what will happen to the box?

• The net force will be zero, and the box will not move.

• The net force will be zero, and the box will move.

• The net force will be greater than zero, and the box will move.

• The net force will be greater than zero, and the box will not move.

A ball is rolling on a flat surface and eventually comes to a stop. Which of the following best explains why the ball stopped?

• The ball ran out of energy.

• The gravity and friction acted on the ball that make it stop.

• The ball's mass increased.

• The ball's speed was too high.

If a moving object collides with a stationary object or an object that is not moving and comes to a stop, what happens to the energy of the moving object?

• The energy disappears.

• The energy is transferred to the stationary object.

• The energy is destroyed.

• The energy remains with the moving object.
