gravitational force
What is a fundamental interaction which causes mutual attraction between all things that have mass
Isaac Newton
Who was an English polymath active as a mathematician, physicist, astronomer, and alchemist
gravity
What is the force that attracts a body toward the center of the earth, or toward any other physical body having mass
static friction
What is a force that keeps an object at rest
net force
What is the sum of all the forces acting on an object
Electromagnetic Force
What is an interaction that occurs between particles with electric charge via electromagnetic fields
first law (Inertia)
What is the tendency of objects in motion to stay in motion, and objects at rest to stay at rest, unless a force causes its speed or direction to change
force
What is the push or pull on an object with mass causes it to change its velocity
fluid friction
What is the force that opposes a motion that takes place within fluids or in between fluids
air resistance
What is the force acting on an object that is moving through air flowing in the opposite direction
weak nuclear force
What is one of the four known fundamental interactions, with the others being electromagnetism, the strong interaction, and gravitation
momentum
What is product of the mass of a particle and its velocity
friction
What is the resistance that one surface or object encounters when moving over another
sliding friction
What is the resistance created by any two objects when sliding against each other
terminal velocity
What is steady speed achieved by an object freely falling through a gas or liquid
strong nuclear force
What is a fundamental interaction that confines quarks into protons, neutrons, and other hadron particles
third law (law Conservation of momentum)
Every action has an equal opposite reaction
mass
What is quantitative measure of inertia, a fundamental property of all matter
rolling friction
What is the type of friction that occurs when a wheel, ball, or cylinder rolls freely over a surface
projectile motion
What is the motion of an object thrown or projected into the air, subject to only the acceleration of gravity
centripetal force
What is a force that acts on a body moving in a circular path and is directed toward the center around which the body is moving.
weight
What is a body's relative mass or the quantity of matter contained by it, giving rise to a downward force; the heaviness of a person or thing.
