What is the momentum of an object of mass m, moving with a velocity v?
(a) (mv)²
(b) mv²
(c) mv²
(d) mv.
Answers
Momentum of a body is the product of its mass and velocity.
Hence, Momentum P = m * v.
It is a vector quantity.
The units of momentum are Kgm/s .
Change in momentum with respect to time gives us the force on the body which is also known as Newton's Second law of motion.
Required option is D.

Hey there! ☺
Nice Question! ♥
------------------------------------------------------------------------
Momentum is the product of two terms i.e. its mass and its velocity.
Hence the correct answer will be - d) mv.
-----------------------------------------------------------------------
Momentum is vector quantity. Because, vector × scalar = vector.
Here, it is the product of the mass which is scalar quantity and the velocity which is a vector quantity.

We can calculate momentum (p) by using this formula.
- p = m × v
Shortly, momentum is the mass which is in motion.
