# An introduction to the science of centrifugal force

## Centrifugal force for kids

The car, at the same time, has largely overcome its own inertia and moved into the leftward turn. However, as it ascends, it burns fuel at a tremendous rate, continuously losing mass. The frictional force supplies the centripetal force and is numerically equal to it. So, at this point, let's say the velocity vector will look like this, the linear velocity vector just to be super clear. In this case, the balance shows the value of the force of gravity on the object. Materials that are denser have greater inertia, and thus are less responsive to centripetal force. This is equal in value to the required centripetal force but acts in an upward direction — the opposite direction to that required. We see it in the spin cycle of a washing machine or when children ride on a merry-go-round. Mass is a measure of inertia, which can be explained by the first law of motion: an object in motion tends to remain in motion, at the same speed and in the same direction that is, at the same velocity unless or until some outside force acts on it.

Since the object is stationary and not accelerating, there is no net force acting on the object and the force from the spring is equal in magnitude to the force of gravity on the object.

This means, then, that the further out on the circle one goes, the greater the average speed.

## Centrifugal force formula

This tendency to maintain velocity is inertia. The latter refers to a geometric shape known as a clothoid, rather like a teardrop upside-down. The rider, meanwhile, is continuing to move forward due to inertia, and thus, his or her body has a tendency to keep moving in the direction of the now-stationary dashboard. Few parts of a roller coaster ride are straight and flat—usually just those segments that mark the end of one ride and the beginning of another. The direction of the individual velocity vector at any given point may be described as tangential; that is, describing a tangent, or a line that touches the circle at just one point. The formula for calculating the angle at which a curve should be banked takes into account the car's speed and the angle of the curve, but does not include the mass of the vehicle itself. MASS: A measure of inertia, indicating the resistance of an object to a change in its motion—including a change in velocity. The increase in normal force on a roller-coaster ride can be attributed to acceleration and centripetal motion, which cause you to experience something other than gravity. Illustrated by Ted Enik. The centripetal force, the action, is balanced by a reaction force, the centrifugal center-fleeing force. At the top of the loop, the roller coaster has gained a great deal of potential energy, or the energy an object possesses by virtue of its position, and its kinetic energy is at zero. This acceleration is equal to the square of its velocity divided by the length of the string.

This force is the centripetal center-seeking force. Hence, at the top of a loop, you feel lighter than normal, and at the bottom, heavier. If there were a railway line running round the Earth's equator, a train moving westward along it fast enough would remain stationary in a frame moving but not rotating with the Earth; it would stand still as the Earth spun beneath it.

Eventually, engineers recognized the clothoid as a means of providing a safe, fun ride. If you want, you could put vectors on top of this.

Consider an object in uniform circular motion: an object moves around the center of a circle so that its speed is constant or unchanging.
