2 Worksheet: Work, energy and power QUESTION 1 1.1 A girl with mass 60 kg slides 3 m down an inclined plane as shown in the picture. a. Calculate the work done on the girl by gravity. b. Calculate the work done on the girl by the normal force. 1.2 A block (5 kg) is pulled by a force of 60 N at an angle of 30 to the ground. The block moves 3,25 ...
Use work and energy principles to calculate a speed or a height or an energy value for a very complex scenario. Some problems involve elastic potential energy. Includes 8 problems.
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?
