... • Force can also be described by intuitive concepts such as a push or pull that can cause an object with mass to change its velocity (which includes to begin moving from a state of rest), i.e., to accelerate, or which can cause a flexible object to deform. A force has both magnitude and direction, ...

... Elevator accelerating upwards Since the net force is 100 N, the upward force (of the scale) and downward force (of the weight) must equal a 100 N upward force. Fnet = F scale – W 100 N = F scale - (50 kg)(9.8 m/s2) F scale = 600 N Therefore, the scale will read 600 N Note that this is a heavier rea ...
