Chapter 7 :
Linear Momentum
Momentum & Its
Relation to Force
Momentum = p = mv
Conservation of
Momentum
During collision, total momentum does not change
=
For more than 2 objects
Internal force cancel,
when the net external force on a system
of objects is zero, the total momentum
of the system remains constant.
the total momentum of an isolated
system remains constant.
Collision & Impulse
Also equals to change in momentum
Conservation of Energy and
Momentum in Collisions
Momentum is conserved in all collisions
Elastic Collision -> KE conserved
Inelastic Collision -> KE not conserved
Inelastic Collision
Some of the initial kinetic energy
is lost to thermal or potential energy
Kinetic energy may also be
gained during explosions addition
of chemical or nuclear energy
Stick together after collision
(only one final velocity)
Collisions in Two or
Three Dimensions
Involve angles
One Equation for each Dimension
