EXERCISE 7 - Rotational Kinematics and circular motion 1. A wheel has a radius of 4.1 m. How far (path length) does a point on the circumference travel if the wheel is rotated through angles of 30°‚ 30 rad‚ and 30 rev‚ respectively? 2.1m‚ 1.2x102 m‚ 7.7. x102m 2. A centrifuge in a medical laboratory rotates at an angular speed of 3 600 rev/min. When switched off‚ it rotates through 50.0 revolutions before coming to rest. Find

law of motion: For every action‚ there is an equal and opposite reaction. How this applies to our bottle rockets that we constructed‚ is that when we release‚ the water and air pressure comes out of the bottom. That pushes against the ground‚ the equal and opposite reaction is the earth pushing back up. Whatever object has less mass moves. In this case‚ the rocket has less mass than what it is pushing against; the earth. When we created our rockets‚ we had to keep all 3 laws of motion in mind

Newton’s second law of motion (Car vs Suv) According to newton’s second law of motion‚ Acceleration is produced when a force acts on a mass. The greater the mass is‚ the grater the acceleration is needed to move forward. This law basically states that a force applied to the objects changes its velocity overtime in the direction of the force that is applied‚ the acceleration is directly proportional to the force‚ as an example‚ if pushing on an object‚ causing it to accelerate‚ and then you push

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

Lab II: Description of Motion in Two Dimensions‚ Problem III: Projectile Motion and Velocity John Greavu February 13‚ 2013 Physics 1301W‚ Professor: Evan Frodermann‚ TA: Mark Pepin Introduction "A toy company has hired you to produce an instructional videotape for would-be jugglers. To plan the videotape‚ you decide to separately determine how the horizontal and vertical components of a ball’s velocity change as it flies through the air. To catch the ball‚ a juggler must be able to predict its position

In 1686 Sir Isaac Newton developed three laws of motion. These laws are involved in every single football play. Whether it is a kickoff‚ pass‚ run‚ or extra point inertia‚ force‚ acceleration‚ momentum‚ and impulse are involved. Newton’s first law is the law of inertia and it states a body continues in its state of rest or of uniform motion unless an unbalanced force acts upon it. Some actions effected by this law are a quarterback throwing a football‚ a running back or receiver running for a touchdown

primarily about Newton’s second law of motion. Newton’s second law of motion states that a net force is required for a body to have acceleration. If a net force is applied on an object‚ then the object will accelerate with respect to the direction of the said force. The body’s acceleration is directly proportional to the net force and inversely proportional to its mass. The experiment conducted was used to verify the relationships specified in Newton’s second law of motion. There were 3 trials‚ and these

Damped Harmonic Motion Erica Partner: Steven November 8‚ 2012 Abstract During this experiment‚ the effects that the size of an object had on air resistance were observed and determined. To do this‚ a spring was set up with a circular object hanging at the end. After the spring constant of 9.0312 N/m was measured‚ equations were used to determine a calculated frequency‚ that being 7.252 Hz. Four trials—each with a different sized‚ same massed object—took place where the object was pulled
