Instead of starting at zero (where he was in A)‚ the man started at -8 under the tree. His speed was increasing at a constant rate so the graph shows him moving in a positive direction from the tree. Explanation for graph’s appearance - after actually performing the activity. Since he is speeding up at a constant rate‚ then his velocity is steadily

intersection. On January 22‚ 2011‚ Felicia Harris was on her way home from work. She was driving East on Highway 43 approaching the intersection of Highway 43 and Sharon Road. Upon reaching the intersection she was driving at a high rate of speed ignoring the speed suggestion signs. By the time she began to apply her brakes it was too late‚ she was into the curve of the road and over compensated to gain control and veered off the road crashing head on into a tree. Unfortunately Felicia did not survive

"Age" Word Problems (page 1 of 2) In January of the year 2000‚ I was one more than eleven times as old as my son William. In January of 2009‚ I was seven more than three times as old as him. How old was my son in January of 2000? Obviously‚ in "real life" you’d have walked up to my kid and and asked him how old he was‚ and he’d have proudly held up three grubby fingers‚ but that won’t help you on your homework. Here’s how you’d figure out his age for class: First‚ name things and translate the

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

Lab Conclusion When comparing the average speed results from part two of the lab and the definition of acceleration‚ you find similarities between the two. First‚ average speed is distance divided by time‚ and we use it to describe the motion of an object moving at changing speeds. We can see this from our lab results from the average speed of the marble traveling down the ramp‚ because it picks up speed. When the marble is released at the top of the ramp‚ the ball doesn’t have the same momentum

fall before landing on the ground with a parachute. As the skydiver falls‚ he or she encounters the force of air resistance. The amount of air resistance is dependent on two variables‚ speed and cross-sectional area. The speed of the skydiver accelerates downwards and gains speed with each second. The increase in speed is accompanied by an increase in air resistance. This force of air resistance counters the force of gravity. Once the force of air resistance is as large as the force of gravity‚ a balance

Many elements have contributed in the evolution of a constant changing society. Technology has been a huge instrument in society’s changes. Technology has opened the gates to unheard opportunities but at the same time‚ those same gates have allowed negative influences to occur within our society. Body image‚ transportation and social media are three outlets that technology has influenced both positively and negatively. Unrealistic expectations of body images pollute the minds of both young men

stopped‚ slowing down‚speeding up‚ and turning provide a sufficient vocabulary for describing the motion of objects. In physics‚ we use these words and many more. We will be expanding upon this vocabulary list with words such as distance‚ displacement‚speed‚ velocity‚ and acceleration. As we will soon see‚ these words are associated with mathematical quantities that have strict definitions. The mathematical quantities that are used to describe the motion of objects can be divided into two categories.
