... We learned earlier that if an object is at rest, then the total of all the external forces acting on it must be zero. If we are also considering the possibility of rotational motion, we must add a second condition for a body at rest: The net torque of all the external forces acting on the body, wit ...

5.7 Some Applications of Newton`s Laws
... In the absence of external forces, when viewed from an inertial reference frame, an object at rest remains at rest and an object in motion continues in motion with a constant velocity (that is, with a constant speed in a straight line). In simpler terms, we can say that when no force acts on an obje ...

... and opposite. We have shown the FBD of both the parts in frame (b). The CM of A-stone is moving under the effect of (1) the gravity force mag, and (2) the force F on it coming from B. These two forces cause the falling of the Astone under gravity, along with rotational motion of the CM.1 In the same ...

Using Vectors to Describe Motion - Galileo and Einstein
... To convey the direction as well as the speed, physicists make a distinction between two words that mean the same thing in everyday life: speed and velocity. Speed, in physics jargon, keeps its ordinary meaning—it is simply a measure of how fast something’s moving, and gives no clue about which direc ...
