A crate is pushed 40 N to the right and pulled 15 N to the right while friction acts 25 N to the left. What is the net force on the crate, and what does the crate do?
A skater pushes a gym wall with a 20 N force to the left. As the skater slides away, friction acts on the skater with 4 N to the left. What is the partner force, and what is the net force on the skater?
A loaded sled slides at a constant speed while a rope pulls it 18 N forward and friction acts 18 N backward. What do these forces tell you about the sled?
A class pulled a box three times. Trial 1: 12 N right, 5 N friction. Trial 2: 20 N right, 14 N friction. Trial 3: 18 N right, 7 N friction. Which trial had the largest net force?
A swimmer pushes water backward with 30 N, and the water pushes the swimmer forward with 30 N. Drag pulls the swimmer back with 12 N. Why do the pair forces not cancel, and what is the net force on the swimmer?
A hand pushes a sliding book 6 N to the right while friction acts 6 N to the left, so the net force is 0 N and the book keeps sliding at a constant speed.
A student drew a book resting on a table with only one arrow: gravity pulling 8 N down. What is missing, and what is the net force on the book once the missing force is drawn?
A toy car has gravity 6 N down, normal force 6 N up, an applied force 14 N right, and friction 5 N left. What is the net force on the car, and what does the car do?
A steel ball feels a 12 N magnetic pull left, a 20 N push right, and 3 N friction left. What is the net force on the ball, and what does the ball do?
A cart is pushed 22 N right against 10 N friction. The push then drops to 10 N right. How does the cart's motion change?
A person pushes a car with 200 N to the right while friction acts 150 N to the left. Which force is the Newton's Third Law partner of the person's push?
A student stops pushing a loaded shopping cart, and the cart gradually slows down as it rolls across the pavement. Which type of force is slowing the cart?
A truck and a small car push against each other bumper to bumper. The truck pushes the car with 900 N forward, and friction on the car is 200 N backward. How hard does the car push the truck, and what is the net force on the car?
A lamp hangs still from a rope while gravity pulls it down with 24 N. What does that tell you about the rope's pull on the lamp?
Three ropes pull a ring lying on a table: 14 N right, 6 N left, and 8 N left. What is the net force on the ring?
A book sits still on a shelf. Gravity pulls it down with 9 N and the shelf pushes up on it with 9 N. What is the name of the shelf's upward push?
A student drew a Newton's Third Law pair as two 30 N arrows on the same skateboard, pointing opposite ways. What is the main error in this drawing?
A 30 N pull to the right and a 12 N friction force to the left act on a box, so the net force is 18 N to the right and the box speeds up to the right.
Two students pull a wagon: 30 N left and 16 N right. Friction acts 5 N right. What is the net force on the wagon, and what does the wagon do?
A balloon pushes air backward with 4 N, so the air pushes the balloon forward with 4 N. Friction on its string acts 1 N backward. What is the net force on the balloon?
