AP Physics 1- Work, Energy, & Power Practice Problems ANSWERS FACT: The amount of work done by a steady force is the amount of force multiplied by the distance an object moves parallel to that force: W = F x cos (θ).
4.1 Use the work-energy theorem to calculate the magnitude of the velocity of the bullet -block system immediately after the bullet strikes the block, given that the frictional force between the block and surface is 10 N. (5) 4.2 State the principle of conservation of linear momentum in words. (2)
The Work–Energy Theorem begins to answer that question by stating that a system gains or loses kinetic energy by transferring it through work between the environment (forces being POWER
Problems: Work, Energy, Power 1) A 10.0 kg mass sliding on a frictionless horizontal surface at 7.00 m/s hits a spring that is attached to a wall. The spring has a spring constant of 5000 N/m. a) Determine the maximum compression of the spring. At maximum compression, the box has a speed of zero.
Work-‐Energy Theorem Practice. Relation between KE and W: The work done on an object by a net force equals the change in kinetic energy of the object: W = ΔKE. This relationship is called the work-‐energy theorem.
Physics Work and Energy Worksheet Solutions Part I 1. Consider two blocks stacked one above the other on a table. Someone pulls the bottom block to the right with a rope in such a way that both blocks accelerate to the right but no slipping occurs at the interface between the top and bottom blocks. Friction at the interface between the two ...
Work, Power, & Efficiency Worksheet. Equations to use: For Ideal Machines: W=F*d P=W/t. Win = Wout. Efficiency=(Wout /Win)x100. Answer on a separate sheet of paper. Show ALL of your work. Use the GUESS or GUPPiES3 method. 1. You move a refrigerator up a 10 meter high staircase.
