Newton's Laws of Motion

Force is.....

• The combining of forces when two or more forces act on an object

• the push or pull that one object exerts on another

• forces that are equal in size and opposite in direction

• forces that are not equal in size and opposite in direction

Net force is.....

• The combining of forces when two or more forces act on an object

• the push or pull that one object exerts on another

• forces that are equal in size and opposite in direction

• forces that are not equal in size and opposite in direction

What kinds of forces change an object's motion?

• Gravity

• All of the above

What factors does friction depend on?

• The roughness of the surface

• The greater the force pushing the two objects together

• The greater the surface area of the two objects touching

• all of the above

Match the following

• Newton's 3rd Law

• All moving objects have momentum. Momentum is transferred between objects in a collision

• Newton's 1st Law

• Every action as an equal and opposite reaction

• Newton's 2nd Law

• A net force acting on an object causes the object to accelerate in the direction of the net force

• Law of Conservation of Momentum

• An object will move at constant velocity until a net force acts on it

Match the following types of frication

• Sliding Friction

• Force between two surfaces that are sliding past each other

• Rolling Friction

• Forces between two surfaces that are NOT moving past each other

• Static Friction

• Force between a rolling object and the surface it rolls on
