All None

(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 …
a large change in momentum over a short period of time
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 or false, chromium reagents are able to oxidize secondary alcohols.
