physics class 11th chapter 5 laws of motion are set of three fundamental principles in physics that describe the behaviour of objects and the forces acting upon them.

The three laws of motion can be expressed mathematically in the following formulas:

• First Law of Motion (Law of Inertia):

F = 0 (If the net external force acting on an object is zero, then its velocity will remain constant.)

• Second Law of Motion (Law of Acceleration):

F = m x a (The net force (F) acting on an object is equal to its mass (m) multiplied by its acceleration (a).)

• Third Law of Motion (Law of Action and Reaction):

F₁ = -F₂ (For every action, there is an equal and opposite reaction force.)
