All Flashcards
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.
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 definition of Center of Mass (COM)?
The point at which the total mass of a system is considered concentrated.
What is the definition of Momentum (p)?
The product of an object's mass and velocity: .
What is the definition of Impulse (J)?
The change in momentum of an object: .
What is the definition of Elastic Collision?
A collision where both momentum and kinetic energy are conserved.
What is the definition of Inelastic Collision?
A collision where momentum is conserved, but kinetic energy is not.
What is the definition of Perfectly Inelastic Collision?
A collision where objects stick together after impact.
