which have equal magnitudes. The signs are: Ax negative; Ay positive; Bx negative; By
negative. Which statement is always true?
(a) A + B = 0.

Newtons Second Law
OBJECTIVE
The purpose of this experiment was to determine the relationship between force and
acceleration. This relationship is determined in a friction-free environment. The
relationship is also used to illustrate the concept of mass.

OBJECTIVE:
The objective of this lab is to understand and estimate the uncertainties between direct
and indirect measurements. In this lab, which is split into three parts; part A, B and C, we used
different methods of measuring the volume, density and ma
As a future mechanical engineer, learning about equilibriums and how
systems react to disturbances while in equilibrium is important because it will
provide me with the ability to predict and control the equilibrium position
that is defined by the constan
