Relier Pairs Physical Science Work & PowerVersion en ligne Module 6 par Stephanie Reid 1 POWER 2 W = F x d 3 WORK 4 F = m x d 5 WEIGHT 6 W = m x g where g = gravity = 9.8 m/s/s 7 P = W/t The amount of work done in one second; the rate of doing work. The formula to calculate force. The SI unit for force is Newtons (N). The formula used to calculate power. Power is the amount of work done in a stated period of time. The formula used to calculate weight. Weight is equal to the Fg (force of gravity on a mass) The formula used to calculate work. If there is no movement of an object, work is not done. Force exerted by gravity. The transfer of energy that occurs when a force causes an object to move.
