... these forces. In each case the tension force of the cord attached to the salami must be the same in magnitude as the weight of the salami because the salami is not accelerating. Thus the scale reading is mg, where m is the mass of the salami. Its value is (11.0 kg) (9.8 m/s2) = 108 N. 19. (a) Since ...

station 1: what is a “force”?
... When a constant force acts on a massive body, it causes it to accelerate, i.e., to change its velocity, at a constant rate. In the simplest case, a force applied to an object at rest causes it to accelerate in the direction of the force. However, if the object is already in motion, or if this situat ...

... You will recall that circular motion is the motion of an object in a curved path about an external axis. This week we will explore a similar situation. Rotational motion is motion of an object in a curved path about an internal axis. The word 'angular' is used to describe motion in a circular path. ...

If one IRF exists, infinitely many exist since they are related by any arbitrary constant velocity vector! In many cases (i.e., Chapters 5, 6 & 7) the surface of the Earth may be viewed as an ...
