A box is pushed with 12 N to the right and 7 N to the left. What is the net force on the box?
Two students pull a rope with 15 N to the left and 15 N to the right. What is the net force on the rope?
A cart has forces of 30 N east, 10 N west, and 5 N east. What is the net force on the cart?
A wagon feels 18 N forward and 24 N backward. What is the net force on the wagon?
A book is pulled upward with 6 N while gravity pulls downward with 6 N. What is the net force on the book?
An elevator has 9000 N upward tension and 8500 N downward weight. What is the net force on the elevator?
A soccer ball has forces of 20 N east, 8 N west, and 5 N west. What is the net force on the ball?
A crate has 40 N right, 40 N left, 12 N up, and 12 N down. What is the net force on the crate?
A skateboard is already moving straight at constant speed. The forward and backward forces are balanced. What will its motion do?
A parked cart has equal forces pushing from opposite sides. If the forces stay balanced, what happens to the cart?
A toy car is moving east, and an unbalanced net force acts east. How does the car's motion change?
A sled slides east, but the net force on it is west. What happens to the sled at first?
A hockey puck glides north on smooth ice. If all forces on it are balanced, what will the puck do?
A bicycle rolls straight ahead. A gust of wind gives it a net force toward the rider's left side, at a right angle to its motion. What change in motion should occur?
A boat moving west has a stronger force acting east than west. How will its westward motion change at first?
A soccer ball at rest is kicked, making the forces unbalanced for a short time. What does Newton's First Law predict?
