11. Momentum & Impulse

If you are involved in a collision where both $p$ (momentum) and $E_k$ (kinetic energy) are conserved, what type of collision has occurred?

If you double your speed, how does the force experienced in a collision change, assuming all other factors remain constant?

In the context of vehicle accidents, how many distinct types of collisions typically occur during a crash?

In the study of types of collisions, the vast majority of collisions can be attributed to four main factors. Which of the following lists correctly identifies these four factors?

If a collision is about to occur and the total kinetic energy of the system is conserved during the event, what type of collision will it be? (i.e., $K\_\mathrm{total,initial}=K\_\mathrm{total,final}$)

Two cars of masses $m_1$ and $m_2$ are moving in the same direction on a frictionless track with speeds $v_1$ and $v_2$, respectively. They collide and stick together, moving as a single unit after the collision. What is the magnitude of the speed $v$ of the combined two-car unit immediately after the collision?

In the context of types of collisions, which type of collision could potentially be avoided by increasing your speed to pass through an intersection before another vehicle arrives?

During an inelastic collision, which of the following quantities is always conserved?

Which type of collision is generally considered the most dangerous for occupants in terms of potential injury severity?

In a perfectly elastic collision between two perfectly rigid objects, which of the following quantities is conserved for the system as a whole?

Two packages of masses $m_1$ and $m_2$ are moving toward each other with speeds $v_1$ and $v_2$ respectively on a frictionless surface. If the packages stick together after the collision, what is their common speed immediately after the collision?

Which of the following best describes a wake effect collision in the context of types of collisions in physics?

In a frontal collision between two objects, which of the following statements is true if the collision is perfectly elastic?

A ball of mass $m$ moving with velocity $v$ collides with a stationary ball of the same mass and after the collision, the two balls stick together and move as one. Which of the following best describes this collision?

Which of the following best describes the difference between an elastic and an inelastic collision?
