Online Custom «Centripetal Force» Essay Sample
The energy involved in adjusting the path for a body in circular motion is known as centripetal force. This is summoned up from Newton’s first law which states that a body in position will always stay in position if some external energy is not applied to it. The law also states that for an object to move through a spherical trail, it should be aided by some energy from the center of rotation, which prevents it from leaving a curvature. Also, for a body to take a corner, it has to change its speed and time which is known as acceleration. A vehicle moving at a steady pace is required to adjust its way in order to take the bend, hence an alteration in acceleration, although the coverage may not be altered. When a car changes direction, the person in it keeps on swinging in the direction they were before the alteration (Hubbard 1996).

Consequently, centripetal force is described as the force which prevents bodies in circular motion from diverging from the curve. It is accompanied by various forces, namely gravitational, frictional, and normal forces. The force of gravity, together with the frictional force, forms the net force which constitutes centripetal force. Centripetal force is essential for whichever sort of movement around any curvature. It is limited neither to loops nor to steady velocity along a particular way (Knudsen et al. 2000).
Centripetal force entails circular motion as it is found within the center of the bend. Gravitational and normal forces work on a body in spherical movement. When an object is in a consistent spherical action, grid energy works on the object to the middle of the curved way as described in Newton’s second law (OpenStax College 2012). The grid force summits to the middle of the loop. It is, therefore, noted that a body in motion has gravity, normal, and frictional forces. The frictional force summits to the middle of the curve and opposes any virtual action; hence the object goes through a direct procession which akes it away from the middle.
The centrifugal force concept has found a lot of applications in devices that rotate: centrifugal pumps, centrifuges, centrifugal governors, and clutches among others. It has also been useful in centrifugal railways, banked curves, and planetary orbits among other things. These devices can be evaluated based on the fictitious force in a coordinated system that rotates in a motion relative to the rotation center or based on the reactive and centripetal forces seen from a reference non-rotating frame. The concept is used taking into account that various forces are of the same magnitude, although the reactive centrifugal and centrifugal forces act in an opposite sense to the core centripetal force.

When the speed of the body goes up, the frictional force also goes up to provide the energy necessary to maintain the body in a circle. When the revolving rate is increased and hence the speed, the frictional force decreases taking the body out of the circle. The gravity energy is equal to the weight of the object and pulls the body towards the center of the earth. The normal force is found between the object and the surface of the earth. It prevents the body from leaving its surface and falling unless an external force pushes it in the opposite direction (Knudsen et al. 2000).
Friction depends on the nature of the surfaces in question. The road is always rough, though sometimes it could be slippery. The friction force goes against the movement of an object, therefore, making it difficult for the body to move to the center of the bend, as the tires are in intermolecular attraction to the path. The two surfaces are pushed closely due to friction.
Centripetal force is evident when a motorcycle is driven along a spherical path and at a steady velocity. The weight of the motorbike is assumed to be the weight of the rider. The complication in the experiment is the gravitational force, which points ddownwards. The normal force summits to the middle of the curve, whereas the frictional force holds the motorcycle on the ground, away from the center of the curvature. At first, the weight of the motorcycle is not altered. The motorcycle is neither speeding nor slowing down, but changing direction. This signifies that the net energy summits to the middle of the movement (Hibbeler 2009).
The weight of the bike summits down, while the normal force summits upwards. The difference between the two forces is the net force, which is the centripetal force. Therefore, normal energy summits to the middle of the curve. From Newton’s first law, an object moves at a constant speed unless an external force is applied to it. According to Hibbeler (2009), spherical movement is not natural; hence some energy is to sustain the spherical movement. The energy to revolve the motorcycle through the corner is offered by the resistance between the wheels and the path.

Alternatively, when extra weight is added to the motorcycle, the normal force and the constituent of the mass summit to the middle of the curve; hence the centripetal force appears. The other constituent of the mass is maintained by resistance; therefore, the grid energy divergent from the curvature is zero and velocity is not altered. The constituents are divided into two equal groups to lessen the calculations. The tires are necessitated to clutch the curve to balance the mass and prevent the motorcycle from diverging from the curve (Hibbeler 2009).
In conclusion, acceleration is required since the speed of an object changes when it goes through a bend. The acceleration is unstable energy which in our case is centripetal force. The energy is provided by the resistance of the path and the tires. When the path is wet, little friction is witnessed as the energy exerted on the tires will not be great. From this perspective, the vehicle will skid out of the spherical movement and might not take the corner.
