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). The units are N. m, which equal a Joule (J). Positive work is done by a force parallel to an object’s displacement.
This test covers Work, mechanical energy, kinetic energy, potential energy (gravitational and elastic), Hooke’s Law, Conservation of Energy, heat energy, conservative and non-conservative forces, with some problems requiring a knowledge of basic calculus. Part I. Multiple Choice 1.

This is the first of two workbooks full of challenging physics problems designed to help you prepare for the Oxford Physics Aptitude Test (PAT). The two workbooks contain many questions of varying difficulty and subject
Work, Energy and Power - Edexcel Physics A-level. Q1. In the sport of curling, two teams of 'curlers' take turns sliding polished granite stones across an ice surface towards a circular target marked on the ice. A stone of mass 19.6 kg is accelerated uniformly for 1.25 s before being released by a curler.
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, and Power “Energy cannot be created or destroyed: it can only be changed from one form to another.” —Albert Einstein Kinematics and dynamics are about change. Simple observations of our environment show us that change is occurring all around us. But what is needed to make an object change, and where did that change go to?
