Relier Pairs Physical Science Work & PowerVersion en ligne Module 6 par Stephanie Reid 1 F = m x d 2 W = m x g where g = gravity = 9.8 m/s/s 3 WORK 4 WEIGHT 5 W = F x d 6 POWER 7 P = W/t The formula used to calculate power. Power is the amount of work done in a stated period of time. The formula to calculate force. The SI unit for force is Newtons (N). The amount of work done in one second; the rate of doing work. 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.
