Force that one surface exerts on another when the two surfaces rub against each other:

The tendency of an object to resist any change in its motion like when your body moves forward after slamming on the breaks of a car:

The force that pulls objects toward each other like how Earth pulls you down:

A unit of measure for force:

Forces that produce a nonzero net force, which changes an object's motion:

Equal forces acting on an object in opposite directions; the object will not move:

What type of force is needed to cause ANY motion like a baseball bat hitting a ball?

The fluid friction experienced by falling objects through the air like leaves floating down from trees:

An object that is thrown like a football:

Any object that orbits around another object in space:

Overall force on an object

Which of the following statements would be an example of a BALANCED force?

You and your brother are using team work to move a heavy TV.

You are pushing on the TV with 60 N of force and your brother is exerting 70 N of force with you on the same side. What is the net force and which statement would be true about the TV?

Using the picture, which team would win?

What type of surface produces LESS friction causing you to slip and fall?
