Conservation of Linear Momentum:This principle states that in a closed system where no external forces act, the total linear momentum before an event or collision is equal to the total linear momentum after.
Collisions: In physics, collisions refer to interactions between objects that result in a change in their velocities. They can be classified as elastic (kinetic energy is conserved) or inelastic (kinetic energy is not conserved).
College Board: The College Board is an organization that develops and administers standardized tests such as AP exams. They set guidelines for what topics are covered in AP Physics C: Mechanics and create exam questions based on these topics.
