Newtons Law

How can two objects of different sizes exert the same amount of force on each other?

Newton’s third law states for every action there is an equal and opposite reaction.

Any object lost by one is gained by the other.

The total momentum of objects prior to hitting each other, will equal the total momentum of the objects after the interaction.

Momentum remains the same during an interaction as long as they are not acted on by an outside force.

In which direction will an object move if acted on by multiple forces?

Newton’s second law states that acceleration depends on both force and mass. It supports the idea that unbalanced forces cause acceleration.

Mass and acceleration are inversely proportional.

There is a direct relationship between force and acceleration.

Unbalanced forces cause acceleration

Why do objects at a constant velocity remain at that velocity?

Newton’s FIrst Law - An object at rest will remain at rest and an object in motion will remain at motion unless acted on by an outside force.

Remember, a net force is the sum of all forces acting on an object Forcenet = mass x acceleration

If an object stops moving or starts moving you know there is a net force.

An object will keep doing what it’s doing unless an outside force acts upon it.
