15.3 Inertia, Momentum, Impulse Flashcards
Define Mass
The amount of matter in a body
Define Inertia
The resistance of a body to alter its state of motion
Define Force
A push or pull on a body that alters its state of motion
Define Impulse
The change in momentum.
Define Momentum
The motion a body possesses
Describe Conservation of momentum
Whenever two bodies collide, the combined momentum of the two is conserved (stays the same).
Decribe Force summation
The correct timing and sequencing of body segments and muscles through a range of motion.
Describe Angular Momentum
Product of moment of inertia and angular velocity
Describe Moment of Inertia
The measure of an objects resistance to change its rate of rotation
Define Impulse
The change of momentum
