• ## Roller Coaster Physics Essay

Physics plays an important role in the mechanics of a roller coaster. The thrilling ride cannot be appreciated, if the physics of a roller coaster is not understood. The loops, bends and hills are all affected by physics. The first hill of a roller coaster is the initial start of energy. Potential energy begins the transfer of energy on the first hill. A chain motor pulls the cars to the top of the hill creating potential energy. Potential energy being defined as the energy determined by its position compared to that of its surroundings. The potential energy is built up due to the height of the roller coaster. Although some of the energy is lost it is eventually turned into kinetic energy. Kinetic energy also referred to as motion energy is…

• ## Spring Fall Lab Report

Purpose The purpose of the lab is to design an experiment to verify the spring constant for an unknown spring, also known as k, how much a spring resists change (compression or expansion). We used a method changing a mass and measured the change in x.

• ## Essay On Kinetic Friction

Purpose: To study sliding friction and to determine the coefficients of static and kinetic friction. Theory: Friction is a force that opposes motion. Static friction prevents an objects being set into motion by an external force. Kinetic friction opposes the progress of a sliding object. Static friction is given by Fs< usn where N is the normal force between the object and its support surface and us is the coefficient of static friction. There-fore, the coefficient of static friction is…

• ## Essay On Roller Coasters

Friction plays a major role in actual roller coaster physics. Once cars are lifted to the top of the hill, gravity takes over, and kinetic energy is transferred throughout the remainder of the ride. Mechanical energy is not consistent. Mechanical energy is the sum of potential energy and kinetic energy. Mechanical energy can either be potential or kinetic. The four types of friction are static, sliding, rolling, and fluid. The normal force is one component of the contact force between two…

• ## Newton's First Law Of Motion Essay

1. C Why: according to Newton’s first law of motion, an object that is free from all outside forces travels at a constant velocity, covering equal distances in equal times along a straight-line path, C is true. 2. D Why: not matter an object is still or is in motion, the object has inertia all the time. Inertia is a nature/property of any objects. 3. D Why: the ship is moving at a constant speed, which is in a balanced status. For the athlete, it would be likely to do a long jump on ground.…

• ## Comparing Kinetics Of A Rigid Body

The similarities and differences of Kinetics of a Particle: Work and Energy and Planar Kinetics of a Rigid Body: Work and Energy. Kinetics of a particle: work and energy shows the particle moving when forces are applied to it and produces work and energy. Meanwhile under planar kinetics of a rigid body shows the rigid body on the plane when forces are applied and produces work and energy. There are similarities and differences between both of it. Kinetics of a particle Planar kinetics of a…

• ## Relationship Between Kinetic Friction

The purpose of this lab is to evaluate the relationship between kinetic friction coefficient and static coefficient as well as measure the coefficients of the two friction. Friction is the force that resists relative tangential movement. Its direction is opposite to the relative velocity. Kinetic friction and static friction are two types of friction. Static Friction happens when the two surface in contact remains relatively stationary to each other. It reaches its maximum value before the…

• ## Pendulum Experiment Lab Report

In this experiment, the objectives were to derive an equation for the tension in the string (which had a mass attached and was revolved in a vertical circle motion). In order to complete this, the velocity of the mass would have to be calculated using the measured tension, and this value would then be compared to the expected velocity. The second objective of this experiment was to observe how mass, velocity, and radius affect the tension of the string. These objectives were reached in this…

• ## Projectile Motion Case Study

Projectile Motion Worksheet A ball rolls off a desk at a speed of 3.0 m/s and lands 0.40 seconds later. How far from the base of the desk does the ball land? How high is the desk? What is the speed and angle of impact? A slingshot is used to launch a stone horizontally from the top of a 20.0 meter cliff. The stone lands 36.0 meters away. At what speed was the stone launched? What is the speed and angle of impact? A ball rolls with a speed of 2.0 m/s across a level table that is 1.0 m…
