100

This force pulls objects toward Earth.

What is gravity?

100

This is the tendency of an object to stay at rest or in motion.  

What is inertia

100

This type of friction occurs when an object moves through a fluid, like air or water.

What is fluid friction?


100

A ramp is an example of this simple machine.

What is an incline plane?

100

This is the formula for speed

What is Speed = Distance ÷ Time?

200

This force opposes motion between two surfaces in contact.

What is friction?

200

This is the formula for force in Newton’s Second Law

What is Force = Mass × Acceleration or F = ma?

200

This force makes it difficult to start moving an object from rest.

What is static friction?

200

A ramp is an example of this simple machine.

What is a wedge?

200

A moving object has this kind of energy

What is kinetic energy?

300

This is the unit for measuring force

What is a Newton?

300

This law states that for every action, there is an equal and opposite reaction.

What is Newton's 3rd law

300

This is the force that acts against the motion of an object.

What is a resistance force?

300

This force keeps objects moving in a circular path.

What is a centripetal force?

300

An object stores this type of energy due to its position.

What is potential energy?

400

This force slows objects down when they move through the air.  

What is air resistance?

400

If the net force acting on an object is zero, this happens to the object

What is it stays at rest or continues moving at a constant velocity?  

400

This happens to an object’s acceleration if the force applied to it increases.

What is the acceleration increase?

400

This type of simple machine is a ramp.

What is an inclined plane?

400

This is the unit of work in physics

What is a Joule?

500

This force keeps planets in orbit around the Sun

What is gravity?

500

This scientist formulated the Three Laws of Motion.  

Who is Sir Issac Newton?

500

This type of force does not require physical contact.

What is a non-contact force, e.g., gravity or magnetism?

500

This is the force that opposes motion between two surfaces.

What is friction?

500

If you push a box and it does not move, this is the amount of work done.

What is zero, because work requires motion?
