Velocity The word‚ velocity‚ originates from the Latin word‚ vēlōcitās‚ meaning swiftness or speed. Velocity is one of the basic words used in mathematics and physics and forms the basis for the more important formulae used in high level study of these subjects. According to the dictionary‚ the definition of velocity is the rate of change of position of an object. In simple words‚ velocity means the distance travelled by an object over some time divided by the time taken by the object to travel

The difference’s between high and low velocity pitchers In my paper I plan to explain the difference between a high velocity pitcher and a low velocity pitcher. Confidence‚ resiliency‚ determination‚ leadership‚ integrity‚ composure and location. All of these words are the best qualities of a pitcher. Pitchers are generals on the bump‚ commanders of the field (All terms for a pitcher on the mound). The team is reflected by their pitcher. There are 2 types of

The relationship between an object’s position and time if it travels in a straight line at a constant speed‚ as well as the relationship between the same object’s speed and time‚ will both result in a linear model. This hypothesis will be tested by using a model car‚ a spark timer‚ and timer tape. Procedure 1.Obtain a model car‚ spark timer‚ half a meter of timer tape. 2.Tape the length of timer tape to the back of the model car. 3.Feed the timer tape through the spark timer‚ setting the

Bolloso Department of Biological Sciences College of Science‚ University of Santo Tomas Espana‚ Manila Abstract Sound is a mechanical wave that is an oscillation of pressure transmitted through a solid‚ liquid‚ or gas‚ composed of frequencies within the range of hearing and of a level sufficiently strong to be heard. It is produced when something vibrates causing

1. Alice throws the ball to the +X direction with an initial velocity 10m/s. Time elapsed during the motion is 5s‚ calculate the height that object is thrown and Vy component of the velocity after it hits the ground. 2. John kicks the ball and ball does projectile motion with an angle of 53º to horizontal. Its initial velocity is 10 m/s‚ find the maximum height it can reach‚ horizontal displacement and total time required for this motion. (sin53º=0‚ 8 and cos53º=0‚ 6) 3. The boy drops

is stronger then the terminal velocity that is when the object is going at a small velocity. Terminal Velocity When there is equal force acting on an object when falling such as gravity and air resistance at that stage it is called constant speed or terminal velocity. When the object is dropped the force of gravity initially is 100% but as it falls the air resistance becomes stronger making the gravity weaker and at one stage there will be terminal velocity. In some cases due to the mass

Determine the time it takes to reach the ground. Answer: t 2 1 6 sec. A particle is dropped from the top of the tower of height h. At the same instant another particle is projected vertically upwards from the bottom of the tower with such a velocity that it will be able to just reach the top of the tower. When and at what height from ground

The relationship between the size of the woodlice and their speed Abstract: How does the physical makeup and size of an organism relate to various activities an organism perform is a topic many people curious about. We wanted to find out if there was any relationship between the body size of woodlice and their speed. We hypothesized that the bigger woodlice have higher speed than smaller woodlice. We conducted an in-class experiment to test our hypothesis. We took ten woodlice and divided

Task question In my task question I am going to study why does the velocity vary downstream? To carry out this investigation we will be going to Carding Mill valley; carding mill valley is located near the border of Wales‚ North West England in Shropshire. (This can be seen on image 1) (Image 1) (Image 1) This means we are collecting primary data which is mainly so we can get accurate and reliable set of results. In order to answer the task question
