The average velocity‚ which is important in physics‚ can be defined as the change in distance divided by the change in time. When applying‚ the average velocity we are looking at real life application as how quickly air temperature is rising or dropping as a hurricane is approaching. Other application we used the average velocity when you want to know the average rate of speed you ran or travel at a given time. When driving your car you might want to know your average velocity from point A to

An experiment was run to determine how does time affect the velocity of the picket fence and how does the time affect the position(displacement) of the picket fence. The proposed hypothesis was that for Velocity- Time graph is that if time increases than velocity will increase because the speed will change over time. The hypothesis for displacement- Time graph is that if time increases position will increase because where the picket fence stared at will change a certain magnitude and direction. The

Physics 211 Experiment #4 Newton’s Second Law – Atwood’s Machine Newton’s second law (FNET = ma) can be experimentally tested with an apparatus known as an “Atwood’s Machine” (See Figure 1.) Two weights of unequal mass‚ connected by a thread‚ are draped over a pulley‚ as shown in the figure. When released‚ the larger mass accelerates downward and the smaller one accelerates upward. Figure (1a): The Atwood’s Machine‚ showing the pulley and the two masses after a run. Figure (1b): A close

(1) Physical and physiological attributes of female team handball players Abstract The main purpose of this article is to review a series of studies (N = 18) on the physical characteristics‚ physiological attributes‚ throwing velocity and accuracy‚ and on-court performances of female team handball players. Studies were selected from a computerized search in electronic databases (Pub Med‚ SPORT Discus) as well as from a manual search. Five main findings emerged from this review: (1) a tall and heavy

or how far she fell. I assumed that she fell about 20 stories‚ or 200 feet (61 meters). If the absence of air resistance is assumed‚ you can find her final velocity using the equation: We know her initial velocity was 0 m/s‚ acceleration due to gravity is 9.8 m/s^2‚ and she fell 61 meters. After plugging in these values‚ the final velocity was determined to be 34.6 m/s. To put this in terms that can be visualized‚ Lois Lane was falling at a speed of about 77mph when superman caught her. I then
