... This statement, “an object that is at rest will remain at rest, and an object that is moving will continue to move in a straight line with constant speed, if and only if the net force acting on that object is zero,” is called Newton’s first law. •Newton’s first law is sometimes called the law of ine ...

Work and the Work-Energy Principle
... • Work is what is accomplished by a force acting on an object (i.e., movement in the direction of that particular force) • Work is a scalar quantity - no direction • It can, however, be either positive or negative. Positive if the object moves at least partly in the direction of the force. Negative ...

Note that the maximum value occurs at α = 45o , which leads to a deflection of the plumb line of β ' 1.7 × 10−3 radians. • Therefore, if buildings were built according to this plumb line they would be tilted by ∼ 1.7milliradians! • As a side note, if you want to “appear” lighter then move to the equ ...
