Impulse from Average Force - Physics

This physics video covers a tutorial on using the mean value theorem for integrals to obtain an equivalent definition of an impulse using the average force. The impulse is a force applied over a time interval. Geometrically, the impulse is the area under the force vs time curve. Hence, different equivalent forms of the impulse can be used in the impulse momentum theorem depending on the physics problem being analysed.

Impulse and Momentum - Physics

This physics video demonstrates how to apply the impulse and momentum theorem to a physics problem. It gives a geometric interpretation of the impulse, which is a force applied over a time interval. An example of an explosion on a spring mass system is used to demonstrate how the impulse and momentum theorem can be used along with the conservation of energy to solve for the deformation of the spring.

Conservation of Momentum - Physics

This physics video covers a tutorial on the conservation of momentum for a system of particles. It explains when momentum is conserved and when it is not. Generally, momentum is conserved when there is no net external force acting on the system. The conservation of momentum is commonly applied to solve for the velocities of particles involved in in elastic and inelastic collisions. Note that the internal forces in the system cancel each other out by Newton's third law, so momentum is not conserved for a single particle subjected to an impulse.
