Gravity and Friction Vocab Flashcards
When gravity is the only force working on an object, the object is in
Free Fall
The velocity at which a falling object travels when the force of air resistance exactly matches the downward force of gravity called the\ the speed at which an object cannot fall any faster
Terminal Velocity
The unbalanced forest that causes an object to move in a circular path is called a ____________ force
Centripetal
A place where matter does not exist
Vacuum
The curved path thrown objects are thrown is called
Projectile Motion
The fluid friction that opposes the motion of objects through air is known as
Air Resistance
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
Weight
An amount of space between two things or people
Distance
the force that attracts a body toward the center of the earth, or toward any other physical body having mass. For most purposes, Newton’s laws of gravity apply, with minor modifications to take the general theory of relativity into account
Gravity
the resistance that one surface or object encounters when moving over another.
Friction
