|
Force equals mass times acceleration.
|
|
|
Objects in motion stay in motion unless acted upon by an outside force.
|
|
|
Every action has an equal and opposite reaction.
|
|
|
All objects are required to have a gravitational force.

Detailed explanation-1: -Newton’s second law states that the acceleration of an object depends upon two variables – the net force acting on the object and the mass of the object. The acceleration of the body is directly proportional to the net force acting on the body and inversely proportional to the mass of the body.
Detailed explanation-2: -Newton’s Second Law: Force His second law defines a force to be equal to change in momentum (mass times velocity) per change in time. Momentum is defined to be the mass m of an object times its velocity V.
Detailed explanation-3: -According to Newton’s second law of motion, the acceleration of an object equals the net force acting on it divided by its mass, or a = F m . This equation for acceleration can be used to calculate the acceleration of an object when its mass and the net force acting on it are known.
