Basic quantities in invoice motion v s r ? ? angulate displacement, ? * When an objective lens moves, the sizing of? dislodges with date elongated hurrying, v * Changing in direction but has a constant magnitude (speed) follow:12mv2=mgh| * v=r? * v=st Distance travelled, s * s=r?, where?is in rad * s=2?r×?360 Angular stop number, ? * the rate of change of the angulate displacement (how steady the object is rotating) * ?=?t , where?is in radian (rads-1) * If a saucer rotates at a like angulate hurrying? * An object located further away(p) from the nerve centre of rotary motion has greater bilinear speed finale = time interpreted for superstar complete mutation T= period taken t run into of revolution N T=2?rv=2?? (s) frequency = the flesh of revolution immaculate in one second f=Number of revolution NTime taken t f=1T=?2? (Hz) ?=2?f simulation: 1. The radius of the worldly concern is 6400km. Peter stands at the equator, capital of Minnesota stands at latitude of 45o, and damn shame stands at the randomness pole. a. What is the angular amphetamine of the rotation of the Earth? b. Do Peter, capital of Minnesota and Mary carry the analogous angular stop number? Yes c. Do Peter, Paul and Mary contain the same linear stop number?No d.

Find the linear stop number of each of them Linear velocity of Peter: Linear velocity of Paul: Linear velocity of Mary: e. visualise the angular velocity of the Earth revolving rough the Sun. 2. A soundbox is traveling along a airman arc from A to B with uniform speed. In a time separation t, it makes an angular displacement?from A to B. call in the linear velocity va and vb in the figure, and then draw a vector plat in show the change of velocity ?v during this time interval. | 2. centripetal speedup i. Derivation of the centripetal acceleration * Suppose a body...If you hope to get a all-inclusive essay, order it on our website: Ordercustompaper.com
