PHY-102 ENERGY AND CIRCULAR MOTION
EXAM SCRIPT 2026 FULL SOLUTION PRACTICE
◉ What is centripetal force? Answer: The net force directed toward
the center of a circular path that keeps an object moving in a circle.
◉ What is tangential velocity? Answer: The linear speed of an object
moving along a circular path, measured at any point along the path.
◉ What is angular velocity? Answer: The rate of change of angular
displacement, typically measured in radians per second.
◉ What is centripetal acceleration? Answer: The acceleration
directed toward the center of a circular path, responsible for
changing the direction of an object's velocity.
◉ What is inertial path? Answer: The path that an object would
follow if no net external force acted on it, typically a straight line.
◉ What is torque? Answer: A measure of the rotational force applied
to an object, calculated as the product of force and the distance from
the pivot point.
, ◉ What is the Law of Universal Gravitation? Answer: A law stating
that every point mass attracts every other point mass in the universe
with a force that is directly proportional to the product of their
masses and inversely proportional to the square of the distance
between their centers.
◉ What is momentum? Answer: The product of an object's mass and
its velocity, representing the quantity of motion an object has.
◉ What is impulse? Answer: The change in momentum of an object
when a force is applied over a period of time.
◉ What is a collision? Answer: An event in which two or more
bodies exert forces on each other for a relatively short time.
◉ What is the Law of Conservation of Momentum? Answer: A
principle stating that the total momentum of a closed system
remains constant if no external forces act on it.
◉ 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.
