... When is Newton’s first law valid? • In Figure 4.11 no net force acts on the rider, so the rider maintains a constant velocity. But as seen in the noninertial frame of the accelerating vehicle, it appears that the rider is being pushed. • Newton’s first law is valid only in non-accelerating inertial ...

... particles can be derived by integrating the equation of motion (F = ma) with respect to displacement. By substituting at = v (dv/ds) into Ft = mat, the result is integrated to yield an equation known as the principle of work and energy. This principle is useful for solving problems that involve forc ...

Circular motion
... Since F=ma and ac=v2/r, the magnitude of the centripetal force equals mv2/r or, written together, Fc=mv2/r. The direction of the centripetal force is the same as the centripetal acceleration (toward the center of the circular path). If this net force were not applied, the object would obey Newto ...
