Newton’s first law of motion is also called the law of ________?

• Mass
• Inertia
• Force
• Velocity

Slamming on the brakes in a moving car makes a passenger move forward against his or her seat belt because

• the passenger has the inertia to keep moving forward
• the passenger is being pushed by the seats of the car
• the passenger is better able to stop themselves in this manner
• the passenger has an equal and opposite force supporting their weight

How long will an object remain at rest, according to Newton's First Law of Motion?

• it can't rest
• until noon
• until an unbalanced force occurs
• as long as there are unbalanced forces acting on it 

Which of these is an example of Newton's First Law, inertia?

• pushing against a brick wall, and the brick wall does not move
• pushing against a stationary wheelbarrow, and the wheelbarrow accelerates forward
• pushing a wheelbarrow full of bricks, and the bricks slide back toward the handles
• pushing a wagon to the top of a hill, and the wagon to the top of hill and the wagon accelerates down the hill without assistance

You are holding a bowl of hot soup while standing in the kitchen. As you begin to move, the soup spills out of the bowl. Upon reflection you realize that

• the soup spilled because of air resistance
• if you had traveled faster this wouldn't have happened
• the soup wanted to stay where it was, but you moved the bowl
• the soup and the bowl act as one body with the same velocity

Which of these is an example of Newton's Second Law, F=ma

• a tug of war where both sides pull equally, and the rope doesn't move

When a Civil War era cannon is fired, the force of the gas produced by exploding powder propels the cannonball forward at a high speed. According to Newton's 3rd law

• the cannon itself moves backward
• the cannon itself does not move due to inertia
• the cannon itself moves forward as well with the momenturm
• the cannon itself moves forward with the inertia of the cannonball

According to Newton's Third Law, what is the equal and opposite force to the downward force of gravity on a man standing on the beach?

• the man pulling upward on the earth
• the force of friction holding the man still
• the pull of the sun keeping the earth in orbit
• the surrounding air pressure keeping the man in equilibrium
