❤1.❤ ✌❤➡Newton’s First Law of Motion⬅❤✌

• A body continues to be in its state of rest or in uniform motion along a straight line unless an external force is applied on it.
• This law is also called law of inertia.

Examples

• (i) When a carpet or a blanket is beaten with a stick then the dust particles separate out from it.
• (ii) If a moving vehicle suddenly stops then the passengers inside the vehicle bend outward.

❤2.❤ ✌❤➡ Newton’s Second Law of Motion⬅❤✌

• The rate of change of linear momentum is proportional to the applied force and change in momentum takes place in the direction of applied force.
• Mathematically F &infi; dp / dt
• F = k (d / dt) (mv)
• where, k is a constant of proportionality and its value is one in SI and CGS system.
• F= mdv / dt = ma

Examples

• (i) It is easier for a strong adult to push a full shopping cart than it is for a baby to push the same cart. (This is depending on the net force acting on the object).
• (ii) It is easier for a person to push an empty shopping cart than a full one (This is depending on the mass of the object).

❤3.❤ ✌❤➡Newton’s Third Law of Motion⬅❤✌

• For every action there is an equal and opposite reaction and both acts on two different bodies
• Mathematically F12 = – F21

Examples

• (i) Swimming becomes possible because of third law of motion.
• (ii) Jumping of a man from a boat onto the bank of a river.

✌❤Note :- ❤✌

✌❤✔Newton’s second law of motion is called real law of motion because first and third laws of motion can be obtained by it.✔❤✌

✌❤✔ $\red {HELLO\:DEAR}$✔❤✌

1. ✌❤✔Newton's first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. ✔❤✌
2. ✌❤✔The third law states that for every action (force) in nature there is an equal and opposite reaction.✔❤✌
