Force as an external effort in the form of a push or pull which moves or tries to move a body at rest, steps or tries to stop a body in motion, changes or tries to change the direction of motion of a body.
Newton's first law of motion does not directly define force; instead, it describes the relationship between force and the motion of an object. Newton's first law is often stated as:
"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 external force."
In other words, the first law states that if the net force acting on an object is zero, the object will remain at rest or continue to move at a constant velocity. If there is a net force acting on the object, it will accelerate in the direction of that force.
Force itself is defined by Newton's second law, which states:
"The acceleration of an object is directly proportional to the net force acting upon the object and inversely proportional to the object's mass."
This law is often expressed by the equation:
F = ma
where:
- \( F \) is the net force applied to the object,
- \( m \) is the mass of the object, and
- \( a \) is the acceleration produced.
So, while Newton's first law describes the behavior of objects when no net force is applied, it is Newton's second law that explicitly defines force and its relationship to motion.
