WebNewton's First Law. Newton's first law of motion states, "An object at rest stays at rest and an object in motion stays in motion, unless acted on by an external force." The easiest way to think about this law is to imagine a ball sitting on a table. The ball sits on the table without moving until you apply a force to it, such as hitting it. WebSolution: The elevator is moving at constant speed, so a = 0, so by N1L there is no net force on the cab. So the tension in the cable is T = mg = 3000 × 9.8 = 29.4 kN Now the work done by the cable moving the elevator 210m is W = Fd6 J The power (= rate of doing work) is P = W/Δt = 6.17 ×106 J / 23s = 2.7 ×105 W = 270 kW daily mail anti cycling

WebPhysics 101: Lecture 5, Pg 12 Apparent Weight Checkpoint You are traveling up on an elevator to the 30th floor of the Sears (OK, Willis) tower. As it nears the 30th floor, your weight appears to be 1) heavier 2) the same 3) lighter F Net, y = ma y N – mg = ma y N = m(g+a) a < 0. so N < mg W = mg N http://hyperphysics.phy-astr.gsu.edu/hbase/elev.html bio layer interferometry octet
