One newton is defined as the force that is required to accelerate a mass of 1 kg by 1 m.s-2 in the direction of applied force.
- Newton is the SI unit of force.
- There is no alteration in body condition without the application of force.
The force is defined as the push or pull on an object with mass that causes it to change its velocity.
F = m × a
m = mass
a = acceleration
