MECH ENERGY Done by Feb break?
Introduction to Mechanical Energy Changes.
CW/HW: Energy Problems
Example of Mechanical Energy Changes:
I take a spring loaded dart gun and fire it into the air. I push on the 0.1 Kg dart with 3 Newtons of force.
What type of energy does it have at each point in its journey?
ENERGY CHANGES ….. IF no friction/heat
Δ ME = Δ ME
GPE + KE + EPE = GPE + KE + EPE
mgh + 1/2mv2 + 1/2kx2 = mgh + 1/2mv2 + 1/2kx2
