Newton’s Three Laws of Motion

1. Law of Inertia

Inertia is the tendency of an object to resist a change in its state of motion. Newton’s First Law of Motion states that an object in motion continues in motion at a constant speed in a straight line and an object at rest remains at rest, unless acted upon by an external unbalanced force. This law can be expressed mathematically as:

F= m x a

where F is the force applied, m is the mass of the object and a is the acceleration.

1. Law of Acceleration

Newton’s Second Law of Motion states that the rate of change of momentum of an object is directly proportional to the applied force, and is in the same direction. The law can be expressed mathematically as:

F = m x a

where F is the applied force, m is the mass of the object and a is the acceleration.

1. Law of Action-Reaction

Newton’s Third Law of Motion states that for every action, there is an equal and opposite reaction. This law can be expressed mathematically as:

F1 = - F2

where F1 is the force acting in one direction, and F2 is the force acting in the opposite direction.
