Cassie is picking up her potted cactus as she cleans her room. She is pulling the cactus up with a force of 20N. Earth's gravity is pulling the cactus down with a force of 15N.
Assume all other forces on the cactus are balanced. Which statement describes the forces on the cactus?
To determine if there is a net force on the cactus, look at the forces:
Cassie is pulling the cactus up with a force of 20N.
Earth's gravity is pulling the cactus down with a force of 15N.
The forces are in opposite directions, and the forces have different magnitudes: 20N and 15N. This means that the forces are unbalanced, so there is a net force on the cactus.
Denise is sitting on a roller coaster cart as it reaches the bottom of a big loop. Earth's gravity is pulling down on Denise with a force of 600N. The seat of the cart is pushing up on Denise with a force of 1,200N.
Assume all other forces on Denise are balanced. Which statement describes the forces on Denise?
Colton is trying to lift a heavy old television. He is pulling up on the television with a force of 500N. Earth's gravity is pulling down on the television with a force of 500N.
Assume all other forces on the television are balanced. Which statement describes the forces on the television?
Brenna is sliding a heavy dresser across the carpeted floor of her apartment. She is pushing the dresser forward with a force of 350N. The carpet is pushing the dresser backward with a force of 380N.
Assume all other forces on the dresser are balanced. Which statement describes the forces on the dresser?
Luke and Eddie are pushing their kayak across the grass toward a lake. Luke is pushing the kayak forward with a force of 400N. Eddie is pushing the kayak forward with a force of 300N. The grass is pushing the kayak backward with a force of 600N.
Assume all other forces on the kayak are balanced. Which statement describes the forces on the kayak?
Three dogs, Scooter, Daisy, and Ace, are playing with a teddy bear. Scooter and Daisy are pulling the teddy bear to the left. Scooter is pulling with a force of 150N, and Daisy is pulling with a force of 160N. Ace is pulling the teddy bear to the right with a force of 200N.
Assume all other forces on the teddy bear are balanced. Which statement describes the forces on the teddy bear?
Liam is using a cane as he takes a walk. Liam is pushing down on his cane with a force of 400N. Earth's gravity is pulling down on the cane with a force of 15N. The ground is pushing up on the cane with a force of 415N.
Assume all other forces on the cane are balanced. Which statement describes the forces on the cane?
Luke and Reid are playing tug-of-war. Luke is pulling on one end of a rope with a force of 230N. Reid is pulling on the other end of the rope with a force of 300N.
Assume all other forces on the rope are balanced. Which statement describes the forces on the rope?
An ice cube is floating in a glass of water. Earth's gravity is pulling down on the ice cube with a force of 0.1N. The water is pushing up on the ice cube with a force of 0.1N.
Assume all other forces on the ice cube are balanced. Which statement describes the forces on the ice cube?
