What is friction? Answer the question for Mrs. Henderson

• The force that opposes motion when two surfaces rub against each other

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

• The movement of an object from one place to another

• A push or a pull that can cause an object to move or change direction

What is Newton's first law of motion?

• Friction is the force that resists motion when two surfaces are rubbing against each other

• The amount of force needed to move an object depends on the object's mass

• Gravity is the force that pulls objects towards the center of the Earth

• An object in motion will stay in motion unless acted upon by an outside force

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

• The force that opposes motion when two surfaces rub against each other

• The force that slows down objects moving through the air

Remember the race car in the video and its speed? What is kinetic energy?

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

• The force that opposes motion when two surfaces rub against each other

• The amount of force needed to move an object depends on the object's mass

• The faster an object is moving the more kinetic energy it has
