Final answer

We use the laws in almost everything we do.

Initial answer

There is always forces acting on each other and the are involved in everything we do

Newton´s Law

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

Acceleration depends on both force and mass. It supports the idea that unbalanced forces cause acceleration.

They remain at a constant velocity because of friction. Say you are driving a car the wheel and the road are causing friction.

Inertia- tendency of an object to resist a change in motion

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

When you hit a volleyball you feel the force on your hand

As force increases acceleration increases and when mass increases acceleration decreases.

Acceleration depends on both force and mass. It helps the idea that unbalanced forces cause acceleration.

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

Unbalanced forces cause acceleration

A tractor has a mass of 3000 kg and has an acceleration of 30 m/s. What is the amount of force the car will give if it hits a barn?

Forcenet = mass x acceleration
