Two students are working together to build a birdhouse. Student 1 applies a force of 10 N to a wooden board in order to slide it across the table to Student 2. If the force of friction resisting the student’s push is 4 N, what is the net force acting on the board?
4 N
6 N
10 N
14 N

Deep Space 1 was a spacecraft powered by an engine that gave off xenon particles to change velocity. It had a mass of 500 kg. Which expression can be used to find the spacecraft’s acceleration if its engine created a net force of 0.10 N?
The drawing shows two identical airplanes at an air show. The airplanes are flying at the same speed. Airplane W is flying 50 m higher than Airplane X. Which statement best describes the energy of the two airplanes?
Airplane W has a greater kinetic energy than Airplane X.
The two airplanes have the same gravitational potential energy but different kinetic energies.
Airplane X has more gravitational potential energy than Airplane W.
The two airplanes have the same kinetic energy but different gravitational potential energies.
A hobbyist collected data about the motion of a toy train on a straight track and then recorded the data in the graph below. Which of these accurately describes the motion of the toy train?
The toy train speeds up while going forward and then slows down.
The toy train slows down while going forward and then moves backward.
The toy train moves forward at a constant speed, slows down, and then stops.
The toy train moves forward at an increasing speed, stops, and then moves forward.
During a lab investigation, students added four 50 g masses to two boxes and arranged the boxes so that they were motionless on a pulley, as shown in the diagram. The students then followed the procedure described in the box. The students recorded their observations after each procedure and reset the pulley system to the original conditions. During which procedures did students observe an unbalanced upward force on Box 1?
Procedures 1, 2, and 3
Procedures 4 and 5
Procedures 3 and 4
Procedures 1, 3, and 5
A clerk at a hardware store performed the activities in the list. Which statement best describes the amount of work performed for the three activities?
Activity 3 required more work than Activity 1, but Activity 3 did not require more work than Activity 2.
Activity 1 required the same amount of work as Activity 3.
Activity 2 required the most work.
Activity 1 was the only activity that required work.
A teacher rubbed a match against a piece of sandpaper. The match started to burn. Which statement best describes the energy changes that occurred?
The chemical energy stored in the match changed to thermal energy and light energy.
The thermal energy stored in the match changed to light energy and chemical energy.
The light energy and thermal energy stored in the match changed to mechanical energy.
The light energy and thermal energy stored in the match changed to chemical energy.
A student graphed the position of a cart during a 7-second time interval. Which statement best describes the cart?
The cart was stationary with a velocity of 0 m/s for the entire 7 seconds.
The cart was stationary except for a short burst of acceleration of 0.5 m/s2.
The cart moved at a constant velocity of 0.5 m/s for the entire 7 seconds.
The cart accelerated at a constant rate of approximately 0.8
m/s2.

As the fuel burns, gases push against the rocket, moving it upward.
As the fuel burns, gases move out of the rocket and reduce air resistance.
As the fuel burns, the mass of the rocket decreases.
As the fuel burns, the rocket moves faster.
