What are the physical quantity conserved in this process
A bullet hits and gets embedded in a solid block resting on a horizontal frictionless table. Which physical quantity is conserved in this process ?
- Momentum and kinetic energy
- Momentum alone
- Kinetic energy alone
- Neither momentum nor kinetic energy
The faster an object is moving and the harder it is to stop, some like as bullet hits and gets embedded in a solid block – whether it be a automobile or baseball. Momentum of an object is equal to the mass times the velocity.
Some about the momentum:
The symbol for momentum is ‘p’
p=m*v (m=mass, v=velocity)
Momentum is a vector, pointing in the direction of the velocity.
Momentum=mass of object x velocity of object
Kinetic energy=(mass of object x (velocity of object)2)/2
