Static and kinetic friction introduction: friction can thought of as a force that opposes motion it never pushes when friction is strong enough to prevent an object from moving, we call it static friction in this lab, you will measure the coefficients of friction between the block and a wooden board to study how an incline effects motion, you will draw.

To address the perceived increasing burdens associated with use of depleted uranium (du) as a kinetic energy (ke) penetrator material, the anccon task group examined use of alternate materials, and considered the impacts of this in four broad areas: performance the industrial base environmental and health factors and life cycle costs. In physics, the kinetic energy of an object is the energy that it possesses due to its motion it is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes the same amount of work is. Moment of inertia is the sum of all the separate small parts so we can write i kinetic energy for the disc is found by integration so figure 6 2 i& ke by definition , the term /pu is the moment of inertia i so we may write /pu 2 /p & r & ke of disc the total ke may be found by integratin g between the limits 0 and r 2 m r kinetic energy of.
