Lesson: Linear MomentumPhysics
In this lesson, we will learn how to identify the definition of linear momentum as the product of the mass and the net linear velocity of an object or a system.
Sample Question Videos
Calculate the magnitude of the average linear momentum of the Earth in its orbit. Use a value of kg for the mass of the Earth and use a value of m for the average orbital radius of the Earth.
A skater of mass 40 kg is carrying a box of mass 5.0 kg. The skater has a speed of 5.0 m/s with respect to the floor and is gliding without any friction on a smooth surface.
Find the momentum of the box with respect to the floor.
Find the momentum of the box with respect to the floor after she puts the box down on the frictionless skating surface.
An avalanche moves a 40 cm thick layer of snow over an area of 100 m by 500 m. The layer of snow moves a distance of m down a hill in a time of 5.5 s. If the average density of the snow is 350 kg/m3, what is the average momentum of the avalanche?
