(long) p151 Ch 7: Impulse and Momentum

Vocabulary flashcards covering key definitions and foundational concepts of Section 7.1 on Impulse and Momentum.

Inelastic collision

A type of collision in physics exemplified by a jousting lance shattering against a shield without unseating a knight, representing one of two basic collision types.

Time-varying force

A force acting on an object that is not constant but changes over time, typically rising from zero to a maximum and returning to zero during contact.

Contact time interval ($\Delta t = t_f - t_0$)

The short duration during which two bodies (such as a bat and a ball) are in contact, typically lasting only a few thousandths of a second.

Average force ($\bar{F}$)

The magnitude of the average force exerted on an object during the duration of contact in a collision.

Impulse-momentum theorem

A key physics theorem formulated using the impulse of a force, linear momentum, and Newton's second law of motion to describe collisions.

Conservation of linear momentum

One of the most fundamental laws in physics that is led to in a natural way from the impulse-momentum theorem.
