Forces: Newton's Laws of Motion/ Work and Energy
1st- motionless unless acted upon
Inertia
a still object
v=0m/s
ex. motionless rocket
ex. Kicked ball
2nd- mass
x
acceleration = net force
F=ma
ex. pulling a wagon
ex. rocket being launched
3rd- Two objects exert same energy
action+reaction forces
same and opposite
ex. trampolines exert same force
ex. force pumps air + launches rocket
Work+Energy
Work
action causes displacement on object
W=Fd
ex. hitting a ball
Energy
capacity to do work
Kinetic Energy
energy in motion
ex. ball falling
Potential Energy
P.E.=mgh
ex. ball's location
position of object
