Exploring Momentum and Impulse Concepts

This video tutorial covers the concepts of momentum and impulse, explaining their definitions, properties, and the relationship between them. Momentum is described as a vector quantity dependent on mass and velocity, while impulse is the product of force and time. The tutorial includes examples to illustrate calculations of momentum and impulse, and demonstrates their interchangeability. Advanced examples are provided to deepen understanding, and the session concludes with a brief update on the equation sheet.

What is momentum a measure of?

• The mass of an object

• The speed of an object

• How difficult it is to stop a moving object

• The direction of an object's motion
