As a skater forms a circle, what force is responsible for making her turn? Use a free body diagram in your answer.ġ0. (c) The car goes over the top slower than this speed?ĩ. (b) The car goes over the top faster than this speed? (a) The car goes over the top at such a speed that the gravitational force is the only force acting? 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 under the following circumstances: (b)The car goes over the top at slower than this speed?Īmusement rides with a vertical loop are an example of a form of curved motion.Ĩ. (a) The car goes over the top at faster than this speed? What other force acts and what is its direction if: If the car goes over the top at just the right speed, gravity alone will supply the centripetal force. ![]() For safety, the cars are attached to the rails in such a way that they cannot fall off. A number of amusement parks have rides that make vertical loops like the one shown in Figure. Race car drivers will take the inside path (called cutting the corner) whenever possible because it allows them to take the curve at the highest speed.ħ. Two paths around a race track curve are shown. Explain how this allows the curve to be taken at the greatest speed. Race car drivers routinely cut corners as shown in Figure. If centripetal force is directed toward the center, why do you feel that you are ‘thrown’ away from the center as a car goes around a curve? Explain.Ħ. ![]() Can any type of force (for example, tension, gravitational force, friction, and so on) be a centripetal force? Can any combination of forces be a centripetal force?ĥ. If you wish to reduce the stress (which is related to centripetal force) on high-speed tires, would you use large- or small-diameter tires? Explain.Ĥ. ![]()
