In Newtonian mechanics, linear momentum, translational momentum, or simply momentum (pl. momenta) is the product of the mass and velocity of an object.Example:1.A semi-truck full of logs has a large mass and must slow down long before a stop light because even with a small velocity, it has a large momentum and is difficult to stop.
2. A four-wheeler moving at a relatively fast velocity has a smaller momentum than the semi-truck because of its small mass and will stop much faster.
3. A bullet, although small in mass, has a large momentum because of an extremely large velocity.

Some of the learners also asked: What do we call the product of mass and velocity?
