Question

how does newton first law work

Answer 1

Newton's first law of motion - sometimes referred to as the law of inertia:

An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

There are two forces acting upon all objects on Earth. One - the Earth's gravitational pull - exerts a downward force. The other force - the push of the solid Earth or ground (sometimes referred to as a normal force) - pushes upward on the object. This is known as balanced force. Since these two forces are of equal magnitude and in opposite directions, they balance each other. The object is said to be at equilibrium. There is no other force acting upon the object. Any other external force acting upon the object is therefore, an unbalanced force.

The behavior of all objects can be described by saying that objects tend to "keep on doing what they're doing" - unless acted upon by an unbalanced force - i.e., unless there is some resistance. If at rest, they will continue in this same state of rest. If in motion with say, for example, a velocity of 5 kmph, they will continue in this same state of motion of 5 kmph. The state of motion of an object is maintained as long as the object is not acted upon by an unbalanced or external force. All objects resist changes in their state of motion - and tend to "keep on doing what they're doing."

There is an important condition that must be met in order for the first law to be applicable to any given mot

Answer 2

It is motion law in which an object at rest stay at rest an object in motion at same speed direction of unless acted upon by unbalanced form
