Momentum Formula
P = mv
Vector quantity
What happens if there is Larger Force?
Theres more momentum
Impulse formula
J = mv
J = F(avg)T
Ft =. mv
J = change in P
Average Force Formula:
F = change in p / change in t
F = m(vf - vi) / t
use kg m/s
How can you change the momentum?
By applying a force.
Momentum
measure of the quantity of motion an object has
Conservation of Momentum
Where the total momentum of an isolated system is constant.
ex) Pool
Conservation of Momentum Formula:
Pi = Pf
Perfect Inelastic Collision
Collision is where particles stick together and move together at the same speed.
collisions where total KE is not conserved (transformed to heat).
Elastic Collisions
Collisions where the kinetic energy of a system is conserved.
KEi = KEf
Conservation Laws:
If the value of a physical quantity is constant in time, quantity is conserved.
Explosions:
Pieces breaking up to different pieces.
Object becoming many and increasing the KE of the system.
Center of Mass
weighted average position of the mass\
= m1×1 + m2×2 / (m1+m2)
