Work Practice Problems Worksheet #1 ANSWER KEY. 1) Amy uses 20N of force to push a lawn mower 10 meters. How much work does she do? Work = Force X Distance Work = 20N X 10m Work = 200 J. 2) How much work does an elephant do while moving a circus wagon 20 meters with a pulling force of 200N?
Work & Power Worksheet. Work is done when a force moves an object or changes its direction. It is measured in. Rule for Work. Work = Force (in Joules) (in Newtons) W = F X s . X Displacement (in metres) Power is the rate at which measured in . Rule for Power.
This collection of problem sets and problems target student ability to use energy principles to analyze a variety of motion scenarios.
In science, work is defined as the force needed to move an object a certain distance. The amount of work done per unit of time is called power. Suppose you and a friend are helping a neighbor to reshingle the roof of his home.
Work, Energy and Power. 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.
