A large rock is motionless on a flat sidewalk. Which statement best explains why the rock remains motionless?
There are no forces acting on the rock.
The only force acting on the rock is directed toward the sidewalk.
The forces acting on the rock are all balanced.
The sidewalk exerts an unbalanced force on the rock.
A leaf fell from a tree branch. The path it followed is shown in the diagram above. Which of these best describes why the leaf fell in a crooked path instead of straight down?
Objects with irregular shapes never fall in straight lines.
Air currents and gravity applied changing and unbalanced forces to the leaf.
The upward force of the air on the leaf was greater than the downward force of gravity.
Once the leaf was in motion, it continued moving in the same direction because the forces were balanced.
NASA's space shuttle program was active from 1981 until 2011. The photograph shows rockers carrying a space shuttle off the launchpad. How can Newton's law of action-reaction be applied to explain the movement of a rocket?
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.
During a demonstration of Newton's laws of motion, a student used the setup shown in Figure 1. The student flicked the index card with a fingertip, and the coin fell straight down into a plastic cup as shown in Figure 2. Which of these best explains why the coin fell straight down into the cup instead of remaining on the index card?
The coin was at rest until the card was removed, so it tended to remain in the same location. Once the card was gone, the unbalanced force of gravity caused the coin to fall.
Moving the card applied an action force on the coin. Since the card was gone, gravity applied a reaction force on the coin.
The card had less mass than the coin, so a smaller force of gravity acted on the card. The larger force of gravity on the coin made it fall.
The acceleration of the coin falling into the cup was equal and opposite to the acceleration of the card.
Four boxes are sliding with constant speed before each box experiences an unbalanced force of 8 N. Which box would experience the greatest acceleration when the unbalanced force is applied?
The box with a mass of 2 kg
The box with a mass of 4 kg
The box with a mass of 6 kg
The box with a mass 8 kg
The list includes six situations. Which objects in the list experience an unbalanced force?
The book, the ball, and the car
The ball, the car, and the bird
The can, the swing, and the bird
The book, the ball, the can, and the swing
A mother and daughter press their hands together and then push apart while ice skating. Immediately after they push away from each other, how does the motion of the mother and daughter change?
The mother moves forward, and the daughter moves backward with a greater acceleration.
Both move forward, but the moves moves with a greater acceleration.
The mother moves backward, and the daughter moves forward with a greater acceleration.
Both move backward, but het daughter moves with a greater acceleration.
The diagrams show forces acting on a toy car as it moves to the right. Which diagram shows the toy car that will most likely accelerate to the right based on these conditions?
Four students push cars filled with sports equipment across the gym. Each student pushes with the same amount of force. Which cart has the greatest change in speed?
Two students are working 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
Which of the following best describes the velocity of an object?
30 m/s
30 m east
30 m/s east
30 m/s2
What is the difference between velocity and speed of an object?
Velocity is the change in distance over time, while speed is the change in velocity over time.
Velocity has a direction associated with it, while speed has no specific direction.
Velocity has no direction associated with it, while speed has a specific direction.
Velocity is the change in speed over time, while speed is the change in distance over time.
