PHY-102 ENERGY AND CIRCULAR MOTION
CERTIFICATION EVALUATION 2026
COMPREHENSIVE QUESTIONS ANSWERS
◉ What is the Impulse-Momentum Theorem? Answer: A theorem
stating that the impulse on an object is equal to the change in its
momentum.
◉ What is an elastic collision? Answer: A collision in which both
momentum and kinetic energy are conserved.
◉ What is a perfectly inelastic collision? Answer: A collision in
which the two colliding objects stick together after the collision,
resulting in maximum kinetic energy loss.
◉ What is an inelastic collision? Answer: A collision in which
momentum is conserved but kinetic energy is not.
◉ What is work? Answer: The transfer of energy that occurs when a
force is applied over a distance.
◉ What is power? Answer: The rate at which work is done or energy
is transferred over time.
