Question

What is momentum in real life?

Answer 1

1. The product of an object's mass and velocity determine its momentum.
2. The equation of momentum is $p=mv$ where $p$ is the momentum, $m$ is the mass, $v$ is the velocity.
3. According to Newton's second law, force is equal to the rate of change in momentum. For a constant mass, force equals mass times acceleration.
   The mathematical relation is:
   $$\begin{gathered} \mathrm{Force}=\frac{\mathrm{change}\mathrm{in}\mathrm{momentum}}{\mathrm{time}} \\ \mathrm{F}=\frac{\mathrm{mv}}{\mathrm{t}} \end{gathered}$$
4. With the assistance of an example, this may be readily understood.
5. Tennis balls are lighter than cricket balls.
6. If the two balls are launched at the same speed. To stop the cricket ball, more power is necessary.
7. When the velocity is constant, more force is required to stop the ball with heavier mass.
8. When two cricket balls are thrown at different speeds, the ball with a higher velocity requires more power to stop.
9. Momentum is a vector quantity that occurs in the velocity direction.
