Question

what is momentum,interia,and conservation of momentum​

Answer 1

Answer:

Linear momentum is the product of mass of the body and the velocity.

$\sf{ \green{ \underline{ \underline{MOMENTUM : }}}}$

• Momentum is defined as the effect produced by force.
• It is the product of mass and velocity.
• It is a vector quantity as it has both magnitude and direction.
• P = m × v where, P = momentum, m = mass and v = velocity.
• Dimension : $\sf [M^1 L^1 T^{-1}]$

$\sf{ \green{ \underline{ \underline{INERTIA : }}}}$

The inability of a body to change its state of rest or uniform motion is called as inertia.

Types of Inertia :

• Inertia of rest.
• Inertia of Motion.
• Inertia of Direction.

$\sf{ \green{ \underline{ \underline{CONSERVATION \:OF\: MOMENTUM : }}}}$

If the external force acting on a system is zero, then the total momentum of a system is conserved and this is known as conservation of momentum.

$\longrightarrow \sf F_{ext} = 0$

$\longrightarrow \sf \frac{dp}{dt} = 0$

$\boxed{\longrightarrow \sf \therefore P = constant}$
