Problem
A student claims that the momentum of any object exactly doubles when its speed is doubled.
Answer the following questions to analyse this statement:
(a) Define linear momentum and state its SI unit.
(b) Using the definition, explain mathematically whether the student’s claim is correct for all objects.
(c) Give one numerical example involving two objects of different masses to illustrate how mass influences the final momentum when speed is doubled.
