What is centripetal and centrifugal forces you may ask. Well centripetal force which means center seeking is a force that compels a body to move in a circular path. While centrifugal force which means center fleeing is an object that travels in a circle that acts like it is experiencing an outward force. Many people confuse the two forces even though they are the opposites of each other. As it says in the physics classroom, “an object which experiences acceleration must also experiencing a net force. The direction of the net force is in the same direction as the acceleration. So for an object to be moving in a circle, there must be an inward force acting upon it in order to cause its inward acceleration. This is sometimes referred to as the …show more content…
For centripetal force to happen a force must act on a object to make it move in a curved path. For example, when a force whirl a stone around on a string, a force must pull on the string to keep it from flying off in a straight line. The force applied to the object is the centripetal force. The faster an object spins the greater the centripetal force needed. The larger the radius of the object the smaller the centripetal force needed. The centripetal force is perpendicular to the motion of an object over a period of time, causing the object to move in a curved path. “To find the force you have to multiply the objects mass, m, by the square of its velocity, v2, and divide the product by the radius of the circle in which it moves.” (2013 encyclopedia) Another thing that affects centripetal force is centripetal acceleration. Here is an example from phys.uaf: “Say you are on a rollarcoaster, centripetal acceleration points towards the center of the circular path of the train, but is felt …show more content…

This question can be answered by having an understanding of centripetal acceleration and centripetal force. Centripetal force described as “the force that keeps an object in its uniform circular motion.”5 The centripetal force in the Greek Waiters Tray is provided by the waiter’s arm.6 Centripetal acceleration is described as “the acceleration needed to keep an object moving in circular motion.”7 The centripetal acceleration is provided by the plate of the Greek Waiters Tray.
Gears are considered wheels with teeth, sometimes called a cog. When the gears come together they are able to make things turn. You need to have at least two cogs to do any work with a gear. Gear come in many different sizes which help them do work. The purpose for gears is to be able to motion from one moving object to another. Gears are used for many reasons such as to increase or increase the rotational speed, to move rotational motion to a different axis, or to keep the rotation of two axis moving at the same time. There are many different types of gears used for different things examples of some would be spur gear, helical gear, worm gear, internal gear etc. Spur gears are one of the most commonly used gears since they’ve been around the longest. Spur gears have teeth that run vertical to the face of the gear. Helical gears are actually similar to the spur gear the difference between them is that the teeth are not perpendicular to the face of the gear, and tend to run smoother due to the larger amount of teeth it has. (Gears and stuff, 2006)Worm gears are u...
Newton’s second law states that when a net force is applied to an object, that object will experience a change in velocity, and will undergo acceleration. That acceleration is proportional to the net force applied, and inversely proportional to the mass of the object. In other words, the heavier an object is, it will require a greater force to move the object the same amount (e.g., distance) as a lighter object. ( https://www.grc.nasa.gov/www/k-12/airplane/newton2.html)The mathematical equation that expresses Newton’s second law is:
Rollercoasters, the star of an amusement park and an achievement in physics, date back decades. In history there is no doubt that people created countless of amazing coasters. They could be record holders, they could do the impossible or they could inspire the design of many other rollercoasters. Nevertheless they are all made because of our knowledge of the laws of physics. Rollercoasters symbolize how we, throughout the years, can use this knowledge to our advantage. Rollercoasters is a way to express physical science while providing safe (if designed correctly) amusement to all.
Tires are thrown from tires because the centrifugal force expels snow, rocks, and other foreign objects.
The acceleration of a body or object is directly proportional to the net force acting on the body or object and is inversely

“A roller coaster is essentially a gravity-powered train (2).” Gravity is the weakest of the four physical forces, but when it comes to roller coasters, it is the dominant one. It is the driving force and what accelerates the train through all the turns and twists. Gravity is what applies a constant downward force on the cars. The deceleration or acceleration mostly depends on the inclination of the angle relative to the ground. The steeper the slope is, the greater the acceleration, and vice versa.
According to mechanical physics, a force is an effect that may cause a body to accelerate. Also as stated in Isaac Newton’s second law of motion, force is a vector quantity (has magnitude and direction) that is proportional to the product of the mass of a body and its acceleration.
In this term paper, I will be relating projectile motion to personal experiences, movies, TV show, and Previous knowledge.
In Chapter 14 (Kinetics of a Particle: Work and Energy) and Chapter 18 (Planar Kinetics of a Rigid Body: Work and Energy), both apply a same concept. It is concept of work and energy to solve the problem. Chapter 14 use the concepts of work and energy to analyze motion of a particle, while Chapter 18 apply work and energy methods to solve planar motion problems. In both chapter, problems that involve force, velocity, and displacement can be solve by using the resulting equation.
Before understanding the physics principles, one must understand the physical design that induces them. A magnetic disk is a flat, circular, rigid sheet of aluminum coated with a layer of magnetic material (can be double sided). The material usually is a form of iron oxide with various other elements added. The disk rotates upon a central axis and a movable read/write head writes information along concentric tracks (circular paths traced out by motion of the disk) on it. Multiple disks can be stacked to store more information. Typically (1985) 11 disks with 22 surfaces, of which 20 are used (minus top/bottom), are manipulated to read/write data.
The science of fluid mechanics is neither new nor biblical; however, most of the progress in this field was made in the 20th century. Therefore it is appropriate to open this text with a brief history of the discipline, with only a very few names mentioned.
Here, we can use the vectors to use the Pythagorean Theorem, a2 + b2 = c2, to find the speed and angle of the object, which was used in previous equations.
