Module 2 Dynamics
Calculations
Kinetic Energy
1/2mv^2 = Ke
The energy an object has due to its motions
Momentum
Impulse
I= delta p
p = mv
The property of an object in motion
COLLISIONS
InElastic
Perfectly
Object stick together but still continue at velocity
Σ P = (Pfinal - Pinitial)/Efficiency
Efficiency = Delta Ek/Ek initial
Elastic
Σ P = Pfinal - Pinitial
Perfectly
Objects bounce off with no energy loss
F = Delta P/Delta t = Mv/t = Ma
Work
Fs=
Delta Ke
Joules
-U=
-(mgh)=
The transfer of energy to an object by froce
Power
Delta W/T=
Fv =
Watts
Friction
The force produced by collision of particles along surfaces of two objects
Ff=μ x N = μ x mg
Forces
Non Contact
Field Forces
Act in a field that gets weaker over distance
Contact
Forces that act by contact
A pull push or twist
Balanced = Continues Velocity or at rest
Newton's Laws
2nd
Force is equal to mass multiplied by acceleration
3rd
For Every action there is an equal and opposite reaction force
1st
A object in constant motion or stationary will continue to be so until acted upon by a net force
