The objective of the first part of the experiment was to derive an expression‚ under conditions with negligible friction‚ for the acceleration of a cart on a level track when it is attached by a string to a hanging mass at the end of the track. With the value of acceleration and the mass of the weight divided by the mass of the weight plus the mass of the cart‚ a value for free fall acceleration (g) could be determined. For the second part of the experiment‚ the objective was to derive a second equation

slightly lower speed than the Earth does‚ the radius of its orbit will slowly decrease‚ and it will move inward toward the Sun. This could bring the probe near the inner planets‚ Venus and Mercury. Acceleration of an Object in Uniform Circular Motion In this activity‚ you will explore the acceleration of an object that travels a circular path at constant speed. Motion of this kind is called uniform circular motion. A. The Gizmotm shows both a top view and a side view of a puck constrained by

It is structured with the conceptual approach. The broad concepts of matter‚ position‚ motion and time; energy; waves; fields; Atomic and Nuclear Physics‚ electronics are considered and each concept forms a part on which other subconcepts are further based. AIMS The aims of the syllabus are to enable candidates

Anti-gravity is the idea of creating a place or object that is free from the force of gravity. It does not refer to the lack of weight under gravity experienced in free fall or orbit‚ or to balancing the force of gravity with some other force‚ such as electromagnetism or aerodynamic lift. Anti-gravity is a recurring concept in science fiction. In Newton’s law of universal gravitation‚ gravity was an external force transmitted by unknown means. Under general relativity‚ anti-gravity is impossible

The Centre of Gravity & its relationship to the Application of Sports Massage Introduction Every object has a centre of gravity‚ which‚ when combined with other factors such as the line of gravity‚ enables an object to balance. If a person or object moves or changes shape‚ the centre of gravity will also move. This is important to remember when discussing sports massage as the therapist is constantly moving‚ making them vulnerable to being unbalanced or unstable. So to be able to conduct a safe

Introduction: Specific gravity or relative density is the ratio of the density of a substance to the density of a given reference material. Specific gravity usually means relative density with respect to water. Temperature and pressure must be specified for both the sample and the reference. The following formula is used- Specific gravity= density of sample/density of same volume of water. Specific gravity is commonly used as a simple means of obtaining information about the concentration of solutions

One day he discovers an unmarked journal with no name‚ which depicts sadistic animal torture experiments‚ boasts of arson fires‚ and the planning for the serial killings of three women. Duncan decides to make amends for his failure last summer by tracking down the owner of the journal by using clues left hidden in the diary. After talking with his

Specific gravity What is specific gravity? Archimedes discovered that the weight of body in air minus its weight in water is equivalent to the weight of the water displaced by the body. Specific gravity is defined as "The weight of a body compared with the weight of an equal amount of pure water at 4°C (4°C is the temperature at which water is densest). When a body is placed in water‚ the volume of water displaced is equal to the volume of the body. When the body is placed in water that it
