What is the direction of the force exerted by the car on the passenger as the car goes over the top of the amusement ride pictured in Figure 8 under the following circumstances: (a) The car goes over the top at such a speed that the gravitational force is the only force acting? (b) The car goes over the top faster than this speed? (c) The car goes over the top slower than this speed?.Amusement rides with a vertical loop are an example of a form of curved motion. Tire friction enables a vehicle to take the curve at significantly higher speeds.Ĭalculations similar to those in the preceding examples can be performed for a host of interesting situations in which centripetal force is involved-a number of these are presented in this chapter’s Problems and Exercises.įigure 8.

This is just about 165 km/h, consistent with a very steeply banked and rather sharp curve. Thus, the magnitude of centripetal force F c is F c = ma c.īy using the expressions for centripetal acceleration a c from a_c=\frac\\ Discussion

For uniform circular motion, the acceleration is the centripetal acceleration- a = a c. According to Newton’s second law of motion, net force is mass times acceleration: net F = ma. If you want to find the net force when you know acceleration and mass. In this case, the force would be the weight the liquid exerts on the bottom of the tank due to gravity. The direction of a centripetal force is toward the center of curvature, the same as the direction of centripetal acceleration. You can calculate the hydrostatic pressure of the liquid in a tank as the force per area for the area of the bottom of the tank as given by pressure force/area units. Just a few examples are the tension in the rope on a tether ball, the force of Earth’s gravity on the Moon, friction between roller skates and a rink floor, a banked roadway’s force on a car, and forces on the tube of a spinning centrifuge.Īny net force causing uniform circular motion is called a centripetal force. Calculate ideal speed and angle of a car on a turn.Īny force or combination of forces can cause a centripetal or radial acceleration.Calculate coefficient of friction on a car tire.By the end of this section, you will be able to:
