It is now appropriate to return to the first law of motion, as formulated by Newton: an object at rest will remain at rest, and an object in motion will remain in motion, at a constant velocity unless or until outside forces act upon it. Examples of this first law in action are literally unlimited. cars going around the loop. There are two forces that will be acting on the cars at the top of the loop. The force due to gravity will be pulling it down (towards the centre). The normal force of the tracks pushing against the cars will be pushing the cars down (towards the centre). These are the two forces that combined will exert theIf the road is banked at the proper angle θ, a car can round a curve without the assistance of friction between the tires and the road and without skidding.

One who ignores these signs is indeed a very foolish driver. Kinetic Energy and the Force of Impact. If control of a car is lost, the usual result is collision, either with another car or with a fixed object. Answer (1 of 10): Because the centripetal force is modifying your momentum along a particular vector. You would, in the absence of centripetal force, continue along a straightline path. However, the centripetal force modifies that vector by inducing an acceleration in a different direction. With...So if you reduce the force of friction by making the road icy, you can't change the direction of your car as fast. You must drive your car more slowly around the curve or your car will skid out. So far, the other forces on the car have been ignored. For example, the force of gravity can affect the motion of your car on a hill.When a car is on a banked curve (that is, the road is not level but is on an angle with the horizontal), there are now forces in both the x and y direction. The important thing to remember here is that the centripetal force is still directed towards the center of the circle, and not down the slope as might be expected. The forces look like:To keep going in a circular path, you must always have a net force equal to mv 2 / r pointing towards the center of the circle. If the net force drops below the required value, you will veer off the circular path away from the center, and if the net force is more than the required value you will veer off towards the center.Example: Car Accelerating on a Curve A car is traveling northwest at 9.0 m/s. 8 seconds later it has rounded a corner and is now headed north at 15.0 m/s.
