Lab {4} Free Fall Motion Abstract Within this laboratory students used a Macintosh computer‚ scientificwork interface‚ and photogate to measure the acceleration of gravity‚ g‚ in a free-fall experiment. Using a “picket fence” dropped through a photo gate with disregard for air resistance; students calculated the results from the charted data and compared it with the accepted value of 9.8 m/s2 discussing any variations and their

A hockey stick exerts an average force of 39N on a 0.2kg hockey puck over a displacement of 0.22m. if the hockey puck started from rest‚ what is the final velocity of the puck? Assume no friction. Your physics teacher walking with the aid of a cane approaches a skateboard of 3.5 kg lying on the side walk. Pushing with an angle of 60 degree down from the horizontal with his cane‚ he applies a force of 115N‚ which is enough to toll the skateboard out of his way. Calculate the initial acceleration

An air Compressor is one of the major energy consuming utilities in any industrial operation and are mainly classified in two types. The classification is based on their construction and operation features. The two main classification of Air Compressor are: 01) Positive Displacement Type 02) Dynamic Type. You will find details of each type from below description. 01) Positive Displacement Type Air Compressor. Positive displacement types compressor are those‚ who mechanically displace

Physics C-110 Module 1 Chapter 1 1. What is science? Science is a body of knowledge that is ever changing. It is made up of not only facts but also theories that are made up of well-tested hypotheses. 2. Distinguish among the scientific fact‚ hypothesis‚ law and theory As stated above‚ a theory is made up of well-tested hypotheses‚ which in themselves are well educated guesses yet to be proven. A fact is something that can change over time even though it was agreed upon by knowledgeable

Find the average final velocity. Start with a ramp height of two workbooks. Release the steel ball from your chosen release point. When the ball leaves the end of the meter sticks‚ start the timer. When the ball reaches the 30 centimeter mark‚ stop the timer. Repeat for 5 trials for each height. If there is an error in the trial‚ do not use that trial‚ and redo that attempt. Enter all data in data table 1‚ then calculate the average final velocities. Find the average acceleration. Start

from the results of the marble’s average speed‚ it was slower when it was at the top of the ramp rather than towards the middle or the end. This is why the marble picks up speed as journeys down the ramp. As for acceleration‚ it is the rate at which velocity changes over time. An object accelerates when there is a change in speed‚ direction‚ or both. Because the marble gains speed as it travels down the ramp‚ it has acceleration. Although the marble only has a change in speed and not direction‚ we can
