Momentum (Kg*m/s) - Coggle Diagram
Momentum (Kg*m/s)
Collisions
Collisions are categorized according to what happens
to the kinetic energy of the system.
Ex. of collision = one billiard ball hitting
another
A collision occurs when two objects free from external forces strike one another.
Types of Collisions
Elastic = two objects collide and bounce
off each other
Explosion = one object becomes multiple
independent objects moving separately
Inelastic = two objects stick together
when they collide
Equations
Explosion: mv = m1
v1^ + m2
v2^
Elastic : m1
v1 + m2
v2 = m1
v1^ + m2
v2^
Inelastic : m1
v1 + m2
v2 = (m1 + m2) v^
Impulse
Impulse = Force * Time Interval
Impulse = Force * Time Interval = the change in Momentum
M = Mass * Velocity
Momentum is a vector quantity. The momentum vector points in the same direction as the velocity vector.
Total M = M1 + M2 +...
Momentum is conserved when objects collide.
