Question

Define momentum and write down its unit.

Answer 1

1. Momentum may be defined as the product of the mass (m) of an object and its velocity (v).
2. It is denoted by the letter ‘p’.
3. Mathematically momentum can be expressed as:
   $$\begin{gathered} p=mv \\ Herep=momentumoftheobject \\ m=massoftheobject\left(kg\right) \\ v=velocityoftheobject\left(m{s}^{-1}\right) \end{gathered}$$
4. The unit of momentum is kg-ms^-1.
