What are the key differences between elastic and inelastic collisions?

Elastic: Kinetic energy is conserved. | Inelastic: Kinetic energy is not conserved.

What are the differences between momentum and kinetic energy?

Momentum: Vector quantity, measures an object's motion. | Kinetic Energy: Scalar quantity, measures energy of motion.

What is the effect of applying an impulse to an object?

It causes a change in the object's momentum.

What happens when no external forces act on a system?

The total momentum of the system remains constant (Law of Conservation of Momentum).

What happens during a perfectly inelastic collision?

The colliding objects stick together and move as one mass, with kinetic energy not conserved.

How do you calculate the Center of Mass (COM) in one dimension?

Use the formula: $x_{cm} = \frac{\sum m_i x_i}{\sum m_i}$ , where $m_i$ is the mass of the i-th particle and $x_i$ is its position.

What is the impulse-momentum theorem?

The impulse on an object is equal to the change in its momentum: $J = \Delta p$ .

How do you apply the law of conservation of momentum?

Set the total initial momentum equal to the total final momentum: $\sum p_{initial} = \sum p_{final}$ .
