What is isaac newton's 1 law of motion?

Answer 1

1st Law: An object at rest will remain at rest, or an object in motion will remain in motion at constant velocity, unless acted upon by an unbalanced force.

2nd Law: The net force on an object is equal to the mass of the object multiplied by its acceleration. (Force = mass x acceleration or F=ma)

3rd Law: For every action, there is an equal and opposite reaction.

Answer 2

Newton's First Law of Motion states that an object at rest will stay at rest, and an object in motion will stay in motion at a constant velocity, unless acted upon by an external force. This is also known as the principle of inertia.

Answer 3

1. First law: Every body remains in a state of rest or uniform motion (constant velocity) unless it is acted upon by an external unbalanced force. [2][3][4] This means that in the absence of a non-zero net force, the center of mass of a body either remains at rest, or moves at a constant speed in a straight line.
2. Second law: A body of mass m subject to a force F undergoes an acceleration a that has the same direction as the force and a magnitude that is directly proportional to the force and inversely proportional to the mass, i.e., F = ma. Alternatively, the total force applied on a body is equal to the time derivative of linear momentum of the body.
3. Third law: The mutual forces of action and reaction between two bodies are equal, opposite and collinear. This means that whenever a first body exerts a force F on a second body, the second body exerts a force −F on the first body. F and −F are equal in magnitude and opposite in direction. This law is sometimes referred to as the action-reaction law, with F called the "action" and −F the "reaction". The action and the reaction are simultaneouse

Answer 4

1. A body at rest will stay at rest until acted on by an outside force

2. The total force force applied to an object is equal to the time derivative of linear momentum of the body

3. For every action, there is an equal and opposite reaction

Answer 5

BY first law Sir Issac Newton, the father of Scinece has introduced about the importance of force. If no force acts on a body which is at rest, then the body would remain in the same rest state.

Also if suppose a body is already in motion with a uniform velocity then it would continue to do so unless an external force acts on it.

So combinging these two, he states:

"Every body continues in its state of rest or of uniform motion along a straight line unless it is compelled by an external force."
