SLO Practice 24-25

A calico cat is asleep in a box. Earth's gravity is pulling down on the cat with a force of 40N.

The bottom of the box is pushing up on the cat with a force of 40N.

Assume all other forces on the cat are balanced. Which statement describes the forces on the cat?

• The forces are balanced, so there is no net force on the cat.

• The forces are unbalanced, so there is a net force on the cat.

Addison is sitting on a roller coaster cart as it reaches the bottom of a big loop. Earth's gravity is pulling down on Addison with a force of 600 N.

The seat of the cart is pushing up on Addison with a force of 1,200 N.

Assume all other forces on Addison are balanced. Which statement describes the forces on Addison?

• The forces are balanced, so there is no net force on Addison.

• The forced are unbalanced, so there is a net force on Addison.

Addison is sitting on a roller coaster cart as it reaches the bottom of a big loop. Earth's gravity is pulling down on Addison with a force of 600 N.

The seat of the cart is pushing up on Addison with a force of 1,200 N.

What is Addison's net force?

• 600 N up

• 1,800 N down

• 600 N down

• 1,800 N up

Audrey is hammering a chisel into a block of marble to carve a sculpture. The hammer is pushing the chisel forward with a force of 40 N.

The block of marble is pushing the chisel backward with a force of 40 N.

Assume all other forces on the chisel are balanced. Which statement describes the forces on the chisel?

• The forces are balanced, so there is no net force on the chisel.

• The forces are unbalanced, so there is a net force on the chisel.

Jared and Austen are trying to lift their friend Matthew onto a tree branch. Jared is pushing Matthew upward with a force of 250 N.

Austen is pushing Matthew upward with a force of 310 N.

Earth's gravity is pulling Matthew downward with a force of 520 N.

What is the net force on Matthew?

• 1,800 N

• 560 N up

• 40 N up

• 40 N down

Cassie is sitting in a paddleboat that is floating on a lake. Earth's gravity is pulling down on the paddleboat with a force of 500 N. Cassie is pushing down on the paddleboat with a force of 550 N. The water in the lake is pushing up on the paddleboat with a force of 1,050N.

Assume all other forces on the paddleboat are balanced. Which statement describes the forces on the paddleboat?

• The forces are balanced, so there is no net force on the paddleboat.

• The forces are unbalanced, so there is a net force on the paddleboat.

Consider the following force: A rolling pin is pushing a mound of cookie dough.

According to Newton's third law, what other force must be happening?

• The mound of cookie dough is pushing on the rolling pin.

• The mound of cookie dough is pulling on the rolling pin.

According to Newton's third law, for every force, there is an equal and opposite force.

Consider the following force: Earth is pulling on a meteorite.

According to Newton's third law, what other force must be happening?

• The meteorite is pushing on Earth.

• The meteorite is pulling on Earth.

According to Newton's third law, for every force, there is an equal and opposite force.

Consider the following force:

Juan is pushing on his friend's wheelchair.

According to Newton's third law, what other force must be happening?

• The wheelchair is pushing on Juan.

• The wheel chair is pulling on Juan

Consider the following force:

Due to gravity, Earth is pulling down on a satellite with a force of 2,000 N.

According to Newton's third law, what other force must be happening?

• Earth is pulling up on the satellite with a force of 2,000 N.

• The satellite is pulling up on Earth with a force of 2,000N.

• Earth is pushing up on the satellite with a force of 2,000 N.
