We used logger pro to accurately measure the orbital period of the spinning mass and used these measurements to determine the interrelated interactions of the specified properties and viewed the results graphically. Data and Calculations The black markings on the string are about 10 cm apart in length‚ measured from the center of the spinning mass.

In fact‚ every object in the galaxy is attracted to every other object in the galaxy. Newton postulated and Cavendish confirmed that all objects with mass are attracted to all other objects with mass by a force that is proportional to their masses and inversely proportional to the square

Roller Coaster For many people‚ there is only one reason to go to an amusement park: the roller coaster. Some people call it the "scream machine‚" with good reason. The history of this ride reflects a constant search for greater and more death-defying thrills. How does a roller coaster work? What you may not realize as you’re cruising down the track at 60 miles an hour is that the coaster has no engine. The car is pulled to the top of the first hill at the beginning of the ride‚ but after

The acceleration is often quoted in multiples of g‚ the standard acceleration due to gravity at the Earth’s surface. This distinction is important because two rotors with different diameters running at the same rotational speed will subject samples to different accelerations. A laboratory centrifuge is a piece of laboratory equipment‚ driven by a motor‚ which spins liquid samples at high

football‚ resulting in acceleration of the football. This is an application of Newton’s first law of motion‚ which implies that a force is required only to change the state of motion. The football starts from rest‚ and the center applies a net force on the ball‚ accelerating it and giving it a velocity. This net force must be greater than the total mass of the football. The amount of force exerted on the football is equal to the mass of the football‚ times the acceleration of the football—Newton’s

to maintain a constant radius of uniform circular motion while ensuring that all of the centripetal force is provided by the clamp and measured on the spring scale. Practice whirling the stopper in a horizontal plane until you can keep the paper clip a short distance just below the bottom of the tube. If the paper clip touches the bottom of the tube‚ then the clamp is no longer supplying the centripetal force. If the paper clips rises or falls appreciably as the stopper whirls then the radius

building them out of wood‚ and finally out of steel‚ was very similar to other creations. People realizing that there are better and more efficient ways to create roller coasters made them what they are today. The one principle that we talked about is centripetal force which occurs on the loops on a roller coaster‚ the inward forces applied on the rider during the loops. In the main part of this essay we learned the physics of roller coasters and how they are applied to the
