Ignore?
momentum
(p) vector quantity describing the quantity of motion or inertia in motion. Recognizes that both mass and velocity have a part in the motion of an object and is proportional to both (is zero …
impulse
a large change in momentum over a short period of time
system
A collection of components organized to accomplish a specific function or set of functions.
elastic collision
A collision in which the total momentum and the total kinetic energy are conserved
impulse-momentum theorem
an impulse causes and is equal to the resulting change in momentum and is in the same direction as the change of momentum
inelastic collision
A collision in which the colliding objects become distorted, generate heat, and possibly stick together.
True or false - momentum is conserved in any collision in an isolated system
True - momentum is conserved between objects unless the system is getting forces from outside the system
False - KE is lost in an inelastic collision
True or false - kinetic energy is conserved in any collision in an isolated system
Center of mass
same as center of gravity
True
True or false, chromium reagents are able to oxidize secondary alcohols.
