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

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

"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

Learning‚ Perception The advert begins with Prof. Ian Johnston narrating the following simulation comparing two identical cars travelling at different speeds and the rate of their respective braking speeds. One car was initially travelling at 65 km/h and the other car travelling at 60 km/h when a change in the road ahead appears ahead a truck blocking their path. The time between when the drivers initially react and the time they come in contact with the truck the car travelling at 65 km/h collides

============================================================================ FACTS: On March 29‚ 1983‚ about 8:28 P.M.‚ Patrolman Michael Aselton of the Barnstable police department was on radar duty at Old Stage Road in Centerville. He saw the defendant’s motorcycle speed by him and commenced pursuit in a marked police cruiser with activated warning devices. The defendant "realized a cruiser was behind him but did not stop because he was `in fear of his license.’" The pursuit lasted roughly six miles through residential

variable of distance has the greatest compression velocity. This compression of Domino’s shares a very close relation to longitudinal sound waves. Longitudinal sound waves work by the compression and rarefaction or particles along a wavelength. The speed of the wave depends upon the denseness of the air.

Results If ski wax can be applied by rubbing‚ pasting‚ spraying‚ or melting then the melt on wax should reduce friction the best because it coats the skis more evenly and creates a thicker protective barrier to the bases of the skis. Consequently‚ this hypothesis was correct because the data captured displayed that the hot wax reduces friction the best‚ see appendix seven‚ eight‚ and nine. Hot melt on wax had the fastest time when the ice disc was slid down the ski and had the highest velocity. It

A typical adult human lung contains about 300 million tiny cavities called alveoli. Assume that the alveoli are spherical‚ and that the volume of a typical human lung is about 2 liters‚ estimate the average diameter of a single alveolus. 3. Two vectors have length and What are the maximum and minimum magnitudes of their vector sum? 4. is a vector

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
