Newtons Third Law

Newton's Third Law States:

Whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first

Action force and reaction force

To every action there is always an opposed equal reaction

Tire pushes on road

road pushes on tire

rocket pushes on gas

gas pushes on rocket

man pulls on string

string pulls on man

Earth pulls on ball

ball pulls on Earth

Recipe for Action-Reaction forces is

if A exerts force on B, then in turn, B exerts force on A

If a semi-truck and a Volkswagen have a head-on collision, which vehicle will experience the greater impact force?

they will both experience the same impact force

Arnold Strongman and Suzie Small pull on opposite ends of a rope in a tug of war. The greatest force exerted on the rope is by:

both the same

how many forces are required for an interaction?

two forces (a pair)

To produce a net force on a system, must there be an externally applied net force ?

yes

As the birds push down on the air with their wings

the air pushes their wings up and gives them a lift.

Newton's 3rd Law of motion is called:

The Law of Interaction
