Multiple Choice

Observe what happens to the motion of the penny. Which of Newton's Laws does this represent?

• Newton's 1st Law, inertia

• Newton's 2nd Law, Force = m x a

• Newton's 3rd Law, action/reaction

Explanation Slide...

Newton's 1st Law of inertia causes the penny to stay in place/drop straight down and enables me to catch it right where my elbow used to be.

Multiple Choice

Watch as Blake pushes the 2 cars of different masses with about the same force. Observe what happens. Which of Newton's Laws does this represent?

• Newton's 1st Law, inertia

• Newton's 2nd Law, Force = m x a

• Newton's 3rd Law, action/reaction

Explanation Slide...

Newton's 2nd Law is the relationship between force, mass and acceleration. The car with less mass travels further when pushed with the same force as the car with more mass.

Multiple Choice

Watch as I propel the washers across the desk. Observe what happens as I use different amounts of force.

• Newton's 1st Law, inertia

• Newton's 2nd Law, Force = m x a

• Newton's 3rd Law, action/reaction

Explanation Slide...

The more force I used, the greater the acceleration of the washers, and the further they traveld.

Multiple Choice

Watch as I send the car down the track. What happens as I increase the force that I am using? Which of Newton's Laws does this represent?

• Newton's 1st Law, inertia

• Newton's 2nd Law, Force = m x a

• Newton's 3rd Law, action/reaction

Explanation Slide...

The more force I apply, the greater the acceleration.

Multiple Choice

Watch as Blake begins to run. What happens to the sheets of paper under his feet? Why? Which of Newton's Laws does this represent?

• Newton's 1st Law, inertia

• Newton's 2nd Law, Force = m x a

• Newton's 3rd Law, action/reaction

Explanation Slide...

The action is Blake pushing off into the ground/paper to run. The reaction is the papper accelerating out the opposite direction!

Multiple Choice

Observe the motion of the washer as I quickly pull the card out from under it. What happened to the washer? Why? Which of Newton's Laws does this represent?

• Newton's 1st Law, inertia

• Newton's 2nd Law, Force = m x a

• Newton's 3rd Law, action/reaction

Explanation Slide...

Because the washer is at rest, it wants to stay at rest. no force is applied directly to the washer, so becuase of inertia, it stays on the table.

Multiple Choice

Which of Newton’s Laws explains a rocket’s movement during launch?

• Newton's First Law of Motion

• Newton's Second Law of Motion

• Newton's Third Law of Motion

• Newton's Fourth Law of Motion

Law states that objects in motion tend to stay in motion, and objects at rest tend to stay at rest unless acted upon by an outside force.

This is the "I'm Chillin" Law, objects will continue to do whatever they are currently doing until they are forced to stop or do something else.

Multiple Choice

The girl on the sled will remain in motion unless

• her motion is changed by magnetic forces.

• she is stopped by an outside force.

• she accelerates at a constant speed.

• the force of friction forcer her to move faster.

Multiple Choice

Which law describes this picture?

• Newton's First Law
• Newton's Second Law
• Newton's Third Law

Multiple Choice

A car is driving at a constant velocity of 75 m/s on the highway headed to Tucson, on a windy day. What is the force acting upon it to continue it's state of motion?

• 0 N, due to "the constant velocity" which means the car is already moving. It does not need force to continue it's state of motion.

• Really? This question again? Obviously it is 75 m/s because of one of Newton's Laws.

• Wait, I do know, I just don't know how to explain it. But, It is one of the laws... right?

• 75 N to the right, due to action and reaction, as well as inertia.

Multiple Choice

What is required for an object to begin moving from rest?

• A balanced force

• An unbalanced force

• No force

• A decrease in mass

Multiple Choice

If you kicked a ball in space it would keep going because there is no gravity, friction, or air friction going against it. It will only stop moving in that direction if something comes into contact with it. This is an example of...

• Newton's Second Law
• Newton's Third Law 

Multiple Choice

What is inertia?

• The force that keeps an object moving in a circle

• The tendency of an object to resist changes in its velocity

• The force that pulls objects toward the center of the Earth

• A ball rolling down a hill speeds up.

• A car comes to a stop gradually when the brakes are applied.

• A book remains at rest on a table until someone moves it.

• A rocket launches off the ground when its engines fire.

Multiple Select

What does it mean when forces are balanced?(Select all that are correct)

• The object is accelerating.

• The object is moving at a constant velocity.

• The object is at rest.

Multiple Choice

What is the effect of mass on inertia?

• More mass means less inertia.

• Mass has no effect on inertia.

• More mass means more inertia.

• Only shape, not mass, affects inertia.

Multiple Choice

If an object is moving with a constant velocity, what can we infer about the forces acting on it?

• There are no forces acting on it.

• The net force acting on the object is zero.

• The object is experiencing a constant force in the direction of motion.

• The object is accelerating.
