Formulas of Force and Laws of Motion
- Newton's First Law of Motion: Also known as the law of inertia, states that an object at rest will stay at rest, and an object in motion will stay in motion with a constant velocity unless acted upon by an external force.
- Newton's Second Law of Motion: This law defines the relationship between an object's mass, its acceleration, and the applied force. The formula is F = ma, where F is the force applied, m is the mass of the object, and a is the acceleration produced.
- Newton's Third Law of Motion: This law states that for every action, there is an equal and opposite reaction. When one object exerts a force on another object, the second object exerts an equal and opposite force.
- Gravitational Force Formula: The formula for calculating the force of gravity between two objects is given by F = (G * m1 * m2) / r^2, where F is the gravitational force, G is the gravitational constant, m1 and m2 are the masses of the objects, and r is the distance between the centers of the objects.
- Tension Force Formula: The tension force in a rope or string can be calculated using the formula T = m * g + ma, where T is the tension force, m is the mass of the object, g is the acceleration due to gravity, and a is the acceleration of the object.
Understanding these formulas and laws of motion is essential in physics to analyze and predict the behavior of objects in motion and the forces acting upon them.

Newton’s First Law
The First Law of Motion by Newton says that every object persists to be in uniform motion in a straight line or in the state of rest unless an external force acts on it.

Newton’s Second Law
The second law of motion by Newton says that the force is equal to the change in momentum( P= m×v) per unit of time.
F = m x a.

Newton’s Third Law
Every time a body exerts a force on another body. The second body simultaneously exerts an equal and opposite force on the first one.
