force, which is itself mass times volume squared divided by the radius. Because the car is on the road, the net vertical force must equal zero. The vertical component is Normal force multiplied by the cosine of theta, which must also equal mass times the force of gravity. Combining these, we get these equations as seen in figure 26:

THE CORIOLIS FORCE There are fictitious forces that come into play when turning a corner in a car, riding in a spinning amusement park ride, and taking off in a jet airplane that everyone experiences. You feel, for example, that you are being forced backward on an airplane when you accelerate down the runway, which is not a force at all. It is instead the force of the seat pushing on you. When you make a tight curve in one direction, you feel like you are being forced in the other direction. In reality, you are going in a straight line but the car is moving in another curved direction. This arises from the use of the car as a frame of reference. These fictitious forces come from using something as a frame of reference that is within a specific system. Passengers will use the car or airplane as the frame of reference, while in physics, the frame of reference is the earth. Using physics, only inertial frames of reference with real forces are used. The car is considered a non-inertial frame of
