Forces Flashcards
Force
Push or pull on an object that can produce movement and change motion
Normal Force
The support force exerted by one stable object onto another
Drag Force
A frictional force exerted on a moving object through air or water
Gravitational Force
The force with which the earth attracts objects towards it
Inertia
The reluctance of an object to change its current state of motion
Momentum
The amount of motion an object has and its reluctance to changing that motion
Momentum formula
mass x velocity
Conservation of momentum
Whenever bodies collide, the combined momentum of the two bodies stays the same
Summation of momentum
The sequential and coordinated movement of each body segment to produce maximum velocity
Impulse
Equal to the change in momentum of an object
Impulse Formula
force x time
Moment of inertia
The resistance of an object to change its angular motion
Moment of inertia formula
mass x radius^2
Angular momentum
The amount of angular motion possessed by a body
Angular momentum formula
moment of inertia x angular velocity
