Question

WHAT IS MEANING OF INERTIA AND MOMENTUM ? plz explain me in hindi.

Answer 1

inertia ek aisi property hai jo kehti hai ki agar ek body chal rahi hai toh vo chalti rahegi jab tak koi external force uspar nhi lagta or agar ek body ruki hui hai toh vo ruki hi rahegi jab tak uspe koi external force nhi lagta. isse newton's first law bhi kehte hai.
momentum matlab mass x velocity

Answer 2

When we ride a bike at a high speed and then immediately stop it then we feel a forward motion which is inertia.
When we roll down a ball it keeps on moving due to momentum.
