Question

state h laws of motion​

Answer 1

Answer:

NEWTON'S LAWS OF MOTION

Explanation:

1. FIRST LAW

it states that " Everybody in the universe stays in a state of rest or of uniform motion along a straight line until unless compelled by an external force to change its state"

2. SECOND LAW

It states "the the rate of change of momentum is directly proportional to the applied force and the change takes place in the direction of the applied force

3. THIRD LAW

It states"to every action there is an equal and opposite reaction"

Answer 2

✴️ $\underline\bold{Laws\:of\:motion}$

$\bold{=>newton's\:first\:law\:of\:motion}$

• it states that a body continues to remain in its states of rest or of uniform motion along a straight line unless & until an external unbalanced force acts on it. It is also known as law of inertia.

$\underline\bold{Example\:of\:Newton's\:first\:law\:of\:motion\:in\:everyday\:life}$

1. A person standing in a bus falls backward when bus starts moving suddenly.

-- This happens because the person and bus both are in rest while bus is not moving, but as the bus starts moving the legs of the person starts moving along with the bus. But rest portion of its body as the tendency to remain in rest because of this the person falls backward if he was not alert.

$\bold{=>newton's\:second\:law\:of\:motion}$

It states that the rate of change of momentum of an object is proportional to the applied unbalanced force in the direction of force.

$\bold{Momentum}$ => It is the product of mass and velocity.

$\bold{=>newton's\:third\:law\:of\:motion\:}$

It states that to every action there is always an equal and opposite reaction.

$\bold{Applications-}$

• working is enabled by third law.

• recoil of a gun.

• rowing of a boat.
