FORCES AND TORQUES IN EQUILIBRIUM
... All external torques on the object balance (so the net torque is zero]. Description of Apparatus In this experiment an object is suspended at rest with up to five forces acting on it; the object remains at rest. The magnitudes and directions of the forces are measured, and calculations are done to v ...

Section 9.1 Impulse and Momentum
... Momentum - product of an object’s mass and velocity. It is a vector quantity that has the same direction as the velocity of the object. It is denoted by “p” (lower case). It is mass in motion. The unit for Momentum is kg m/s. To find Momentum you use p = m*v Δp = mΔv FΔt = mΔv = mvF – mvI = Δp = pF ...
