At that instant, the Flap Flap passengers endured 12 Gs on the base of their spines. That Normal force was much stronger than the force of gravity, and it was exerted on the passenger sitting on the wooden cart. Once the coaster reached the bottom of the track, the Normal force is much bigger than the force of gravity. Looking at the images, we see that because the net force points inward. The Flip Flap was a perfect circle, so the loop’s curvature was constant. But, for the Flip Flap, once that coaster started to go back down, gravity began to pull on it. Again, that’s the Normal force that we feel, and the Normal force is minimal. The net force will always have an inward direction on the loop.Īs the coaster moves to the top of the loop, passengers should feel a sense of weightlessness. As a result, as the velocity moves us forward, the net force on our bodies keeps constantly changing. What we actually feel on our body is the Normal force. Two vector forces are acting on the body, the Normal force and gravity’s force. If you have even been in a looping roller coaster, you will feel heaviest at the bottom and the lightest at the top. What went wrong? Well, for all looping roller coasters, as a roller coaster is going into a loop, the speed at which we move provides us the inertial velocity to get to the top of the loop and then back down again. We are accelerating towards the earth at 9.8 m/s 2. Roller coaster, there’s no Normal force pushing up on us and we are freeįalling at 9.8 m/s 2, which is the force of gravity pulling us down.Īnd, again, since our bodies are accelerometers, we feel this…and it’s awesome. The force W is the weight of the box, and the force N is the upward force that the table exerts on the box.īut when we are falling from a high point on a Even though the box is at rest on the table, two forces are acting on the box, the Normal force N, and the force of weight W. The image of the box on the table helps to explain this. The Normal force is perpendicular to the surface that you stand on. It is called Normal because that’s a synonym for perpendicular. It’s a contact force that we get from the earth, also known as the Normal force. That force that we are used to daily is just 1 G. We feel gravity on our bodies as we stand or sit.
