dp/dt =
F; slope of momentum vs time is force
integral of force versus time is
impulse / change in momentum
-dU/dx =
F; negative slope of potential energy cs position graph
integral of F(x) or force vs position =
work; negative change in potential energy
dW/dt =
power
integral of P(t) or power vs time =
work (energy transferred)
dL/dt (derivative of angular momentum)
= torque
area under graph of torque is
angular momentum
P/v =
Force
slope of energy vs time
= power (power = W / t)
value of dU/dx tells you ___ whereas -dU/dx tells you ___
how steep hill is and which way is “up”; which way the ball would roll
