being grounded in their court. Fitness components needed for volleyball are: * Speed * Balance * Agility * Speed * Reaction * Hand-eye coordination Speed: Volleyball hits that are fast and accurate make it difficult for the opponents to counteract. Trajectory is extremely essential‚ as the ball must arc high enough to pass over the net. However if a player generates too much speed while hitting the volleyball over the net‚ it is more likely that the ball will travel

Lab 4: Methods of limits Elizabeth Bryan Florida State University Lab 4: Method of limits. Sound waves are created when an object vibrates. They have two main components: frequency (pitch; measured in Hertz (Hz)) and amplitude (loudness‚ intensity; measured in decibels (dB)). The method of limits is a psychophysical method in which a particular dimension of a stimulus‚ or the difference between two stimuli‚ is varied incrementally until the participant responds differently. The change in stimulus

NAME: DATE: LIMITS OF READING (LOR) MEASUREMENTS In science‚ the results of experiments are never 100% reliable. There are always experimental errors involved. It is therefore important to be able to assess the magnitude of these and their effect on the reliability of the final result. It is important to differentiate between the accuracy and the precision of a result. The accuracy of a measurement refers to the "closeness" of a numerical value to the actual or theoretical value. The accuracy

Discussions:- I. Objective. To measure the speed of sound waves in air. ll. Abstract. This experiment tried to determine the speed of sound waves. To determine the speed‚ a resonance tube full of water was used and five different tuning forks of known frequency. Each fork was struck above the water level and the water level was slowly moved down until a resonance was heard. The distance where the resonance occurs were recorded and the speed of the waves

the vibration of an object; once the item vibrates the sound waves then radiate outwards until they are either stopped or they die out. A sound wave has three characteristics: Frequency‚ amplitude and phase. These three allow us to measure pitch‚ speed and potentially the energy of the wave as well. Sound travels when particles interact with each other when a sound source effect the first particle of a medium. This then causes the particle to vibrate backwards and forwards which then means that

Dr. Reginald Lear took over as the School’s president and was offered a compensation package‚ which ranked highly for college presidents exceeding $700‚000.

all of physics." The deepest mystery in all of physics is that in a vacuum all bodies fall with the same constant acceleration. 2. In the next sequence‚ we see a person diving from a board and a leaf falling from a tree. It is stated that the speed of a falling body increases as it falls. If the statement concerning falling bodies is true‚ then why does the leaf seem to fall so much more slowly than the diver? The leaf seems to fall much more slowly because it has less mass then the diver which

By the time the plane’s sound detector receives the horn’s sound the plane has travelled a distance equal to half its altitude above the ocean. Assuming it takes the sound 2.00 s to reach the plane‚ determine (a) the speed of the plane and (b) its altitude. 4. (17P40) A block with a speaker bolted to
