ACCELERATION AND FORCE IN CIRCULAR MOTION
... at constant speed so its acceleration ~a is purely radial. The car’s speed is such that the road exerts only a normal force on the car. The turn is banked at angle θ, which is also the angle by which the road force is off the vertical. The resultant (net, total) force on the car is labeled F~r . of ...

... In this topic we consider the motion of an object of constant mass m moving in a straight line and subjected to a system of forces. In previous topics, the forces have been constant, and since F = ma, the acceleration was also constant, so the constant acceleration formulas could be used. However, i ...

Centripetal Force
... As shown in Figure 1, if the Force is too small or the object traveling too fast, then it will move outward from the circular path. If the object travels too slowly or the Force is too large, then it will fall inward toward the center. For a given speed and radius, there is only one magnitude of For ...
