Newtons Third Law

of Motion

Every object will remain at rest or in a uniform motion unless compelled to change its state by the action of an external force.

The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.

Third Law in

Action

When birds flap their wings, the wings push the air downward and that then propels the bird upward to the sky

For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object.

F= M x A

Example of

Newtons Third Law

We couldn't play baseball

without Newtons third law

Force is equal to Mass times Acceleration. The greater the mass, the more force is required for acceleration.

Mass and acceleration are inversely related.

Examples of this law:

A net force is the sum of all forces acting on an object and is capable of accelerating a mass. For instance, if the wheels of a car push it forward with 5 Newtons and drag is 3 Newtons, the net force is 2 Newtons forward. Therefore, the motion of the car would be positive to the right.

The pitcher pushes his hand off of the ball causing the ball to propel forwards

Force

F=-F

The two forces are equal however the second force is negative because it is the exact opposite of the first force

The bat hits the

ball causing the ball

to fly through the air

-Sliding a hockey puck

-Kicking a ball in space

-Driving a car and crash

-Spaceship in space

-Airplane

-Model Rocket

-Kite

A rocket ship moves upward by a force that is equal and opposite to the force of fuel coming out the back

The first force can be looked at as the action and the second force as the reaction

His feet push downward on the ground to propel him forwards as he runs

to catch the ball
