Uniform Circular Motion – a constant motion along a circle; the unfirom motion of a body along a circle Frequency (f) – the number of cycles or revolutions completed by the same object in a given time; may be expressed as per second‚ per minute‚ per hour‚ per year‚ etc.; standard unit is revolutions per second (rev/s) Period (T) – the time it takes for an object to make one complete revolution; may be expressed in seconds‚ minutes‚ hours‚ years‚ etc.; standard unit is seconds per revolution

When relevant‚ data collected should be presented in a table. Objective: To explore the acceleration and force of an object that travels a circular path at constant speed. Motion of this kind is called uniform circular motion. Part 1: Centripetal Acceleration 1. The Gizmotm shows both a top view and a

ASP 0501 EXERCISES – circular motion 1 A car travels at a constant speed around a circular track whose radius is 2.6 km. The car goes once around the track in 360 s. What is the magnitude of the centripetal acceleration of the car? 2 An astronaut in a chamber moves on a circular path‚ much like a model airplane flying in a circle on a guideline. The chamber is located 15 m from the center of the circle. At what speed must the chamber move so that the astronaut is subjected to 7.5 times the acceleration

Case Study- Research in Motion (RIM) “Leading the Way the World Communicates” “It is the partnership and teamwork that underpinned the company and transformed the world!” The blackberry has challenged a number of very basic concepts in work and life. It eliminates distance and time and challenges the boundaries between work and home. It has enabled us to do things that would have been impossible 10 years ago. As a company itself RIM breaks the status quo by encouraging teamwork‚ empowering

Perpetual Motion (of machines) is defined as “The motion of a machine that‚ once activated‚ would run forever unless subject to an external force”; is it possible? Let’s start off where it all began. Ever since the 8th century man has been attempting to build Perpetual Motion Machines‚ many were designs of a system of weights on a wooden wheel.[1] These work in a simple cycle starting with the weights on the left side‚ these weights hang close to the wheel resulting in a lower torque; but when the

Newton ’s laws of motion Newton ’s laws of motion are three physical laws that form the basis for classical mechanics. They describe the relationship between the forces acting on a body and its motion due to those forces. They have been expressed in several different ways over nearly three centuries and can be summarized as follows: 1. First law: The velocity of a body (a state of rest or of uniform motion in a straight line) remains constant unless the body is compelled to change that state

Projectile Motion PHYS111 Formal Report 2 University of Canterbury Campbell Moulder Abstract The force of gravity is said to be a constant of 9.81 ms-2 (3). This can be proved by measuring the projectile motion of a bouncy ball and plotting a ∆Vertical Velocity vs. Time graph‚ the gradient of which should equal the constant force (acceleration due to) of gravity. Our gradient value of 10.26±0.49 ms-2 is consistent with the actual value of 9.81 ms-2. Introduction A projectile is an

PERFORMING A MOTION STUDY AND PERFORMING A TIME STUDY A time and motion study (or time-motion study) is a business efficiency technique combining the Time Study work of Frederick Winslow Taylor with the Motion Study work of Frank and Lillian Gilbreth (not to be confused with their son‚ best known through the biographical 1950 film and book Cheaper by the Dozen). It is a major part of scientific management (Taylorism). After its first introduction‚ time study developed in the direction of establishing

There are the two components of the projectile’s motion - horizontal and vertical motion. And since perpendicular components of motion are independent of each other‚ these two components of motion can be discussed separately. The goal of this part of the lesson is to discuss the horizontal and vertical components of a projectile’s motion; specific attention
