WGU C165 CORE MAIN UPDATED QUESTIONS
AND ANSWERS SURE A+
✔✔Newton's First Law - ✔✔An object at rest stays at rest and an object in motion stays
in motion with the same speed and in the same direction unless acted upon by an
unbalanced force.
✔✔Mass - ✔✔the amount of matter in an object
✔✔Inertia - ✔✔The tendency of an object to resist a change in motion
✔✔Newton's Second Law - ✔✔Force equals mass times acceleration
✔✔Newton's Third Law - ✔✔For every action there is an equal and opposite reaction
✔✔Friction - ✔✔A force that opposes motion between two surfaces that are in contact
✔✔Gravity - ✔✔Gravity is the force by which a planet or other body draws objects
toward its center. The force of gravity keeps all of the planets in orbit around the sun.
✔✔gravitational force - ✔✔an attractive force that acts between any two objects
, ✔✔Momentum - ✔✔the force or speed with which something moves
✔✔law of conservation of momentum - ✔✔One of the most powerful laws in physics is
the law of momentum conservation. ... For a collision occurring between object 1 and
object 2 in an isolated system, the total momentum of the two objects before the
collision is equal to the total momentum of the two objects after the collision.
✔✔work - ✔✔Force exerted on an object that causes it to move
✔✔Energy - ✔✔the ability to do work
✔✔potential energy - ✔✔Energy that is stored and held in readiness
✔✔kinetic energy - ✔✔the energy an object has due to its motion
✔✔gravitational potential energy - ✔✔Energy stored by objects due to their position
above Earth's surface.
✔✔chemical potential energy - ✔✔the energy stored in the chemical bonds of a
substance
✔✔elastic potential energy - ✔✔the energy of stretched or compressed objects
✔✔electrical energy - ✔✔The energy of electric charges
✔✔electromagnetic energy - ✔✔Electromagnetic energy is a term used to describe all
the different kinds of energies released into space by stars such as the Sun. These
kinds of energies include some that you will recognize and some that will sound strange
✔✔thermal energy - ✔✔Heat energy
✔✔Law of Conservation of Energy - ✔✔the law that states that energy cannot be
created or destroyed but can be changed from one form to another
✔✔wave - ✔✔A disturbance that transfers energy from place to place
✔✔oscillation - ✔✔the act or state of swinging back and forth with a steady,
uninterrupted rhythm
✔✔Equilibrium - ✔✔A state of balance
✔✔medium - ✔✔The material through which a wave travels is called a
Gases (air), liquids, solids
