Chp 13 Vocab Flashcards
A measure of the amount of matter in object
Mass
A force of attraction between objects that is due to their masses
Gravity
A measure of the gravitational force exerted on an object
Weight
The constant velocity of a falling object when the force of air resistance is equal in magnitude and opposite direction to the force of gravity
Terminal velocity
The motion of the body when only the force of gravity is acting on the body
Freefall
The curved path that object follows when thrown around, launched, or otherwise projected near the surface of Earth
Projectile motion
The tendency of an object to resist being moved or if the object is moving to resist a change in speed or direction until an outside force acts on the object
Inertia
The force that opposes the motion of objects through air
Air resistance
A place in which there is no matter
Vacuum
Unbalanced force that makes things move in a circular motion
Centripetal force
Property of moving objects that depends on mass and velocity
Momentum
Energy of position or shape
Potential energy
Ability to do work
Energy
Energy of motion, depends on mass and velocity
Kinetic energy
When a force is exerted through a distance
Work
