Laboratory Coefficients of Friction Discussion: Friction is the force that resists motion and can be determined in either static situations or kinetic situations using the following equation: [pic] Static friction is the amount of friction that resists the start of motion and kinetic friction resists an object’s continued motion. The coefficient of friction depends on a number of factors including surface area and the types of surfaces in contact. The only way to determine a coefficient of friction

Coefficient of Friction- Post Lab Abstract The purpose of the experiment was to determine to coefficient of friction on a block sliding across a horizontal plane‚ and on the same block sliding down an inclined plane. This was done by first testing block‚ and how much weight on a string was needed to move the block at a constant velocity using a pulley system. The block weighed 0.2385 kilograms‚ and needed a hanging mass of 0.05 kg to move at a constant velocity. This means the coefficient of

bloomberg beta interpretation Beta definition A measure of an asset’s risk in relation to the market (for example‚ the S&P500) or to an alternative benchmark or factors. Roughly speaking‚ a security with a beta of 1.5‚ say‚ will move 50% more than the market. So if the market goes up by 20% the security’s price will go up by 30%. According to asset pricing theory‚ beta represents that part of the risk of the security called systematic risk that cannot be diversified away. When using beta‚ there are
