100

This is a push or a pull.

What is a force?

100

This law states that every action has an equal and opposite reaction.

What is Newton's third law?

100

This is the rubbing force  that acts against motion between two touching surfaces.

What is friction?

100

Where the forces acting on an object are unbalanced, the net force is not this number/quantity.

What is zero?

100

True or false: The time for an action-reaction situation is instantaneous.

What is true?

200

This word describes the total force felt by and object.

What is net?

200

This law can be expressed with the equation a=F/m, or acceleration is equal to net force over mass.

What is Newton's second law?

200

This type of friction enables one to ride a bike without skidding and falling.

What is rolling friction?

200

This force keeps bridges from breaking when people walk across them.

What is normal force?

200

True or false: The force of gravity exists between any two objects that have mass.

What is true?

300

When forces cancel each other out, they are said to be this.

What is balanced/what are balanced forces?

300

This law states that an object in motion will stay in motion and an object at rest will stay at rest unless acted upon by an outside force.

What is Newton's first law?

300

Applying the brakes to a moving vehicle uses this type of friction.

What is sliding friction?

300
When a person pushes a wall, what is the equal and opposite force/reaction?

The wall pushes back.

300

True or false: While static friction keeps an object at rest, rolling friction slows down an object that slides.

What is false? Sliding
400

In order to know how a force will affect an object, this quality must be known.

What is direction?

400

According to Newton's first law, an object in motion moving at a constant speed will continue moving in this type of line unless a net force acts upon it.

What is a straight line?

400

This type of friction impacts objects in the air (do not use "friction" in the answer).

What is air resistance?

400

This term describes the speed an object reaches when the force of gravity is balanced by the force of air resistance.

What is terminal velocity?

400

True or false: If a net force acts at an angle to the direction an object is moving, the object will follow a straight path.

What is false? Curved
500

Give the formula for force.

Force equals mass times acceleration.

F=m(a)

500

Force is measured in this unit.

What are Newtons?

500

If a projectile is launched, what other force besides friction will eventually bring it down.

What is gravity?

500

This quantity is the gravitational force of any object near Earth's surface. (hint: this quantity is acceleration due to gravity, you must give the correct number and unit).

What is 9.8 meters per second squared?

500

True or false: an object at in motion will constantly move in an elliptical orbit unless a net force acts upon it.

What is false? straight line.
