What is Newton's first law? Give an example to support your answer.
An object will not change its motion unless a force acts on it (object in rest will stay at rest) e.g people flying forward when a car stops quickly.

What is net/resultant force? What does it show us?
Net or resultant force is the sum of all the forces acting on an object. It shows us whether the object will accelerate in any direction or remain still.

Describe Neton's 2nd law. Give an example.
The greater the mass of an object, the greater the force required to move it. e.g. more force is required to accelerate an elephant than a mouse.
