Yes, keyboard bullies are running the show and may see some light after watching your two shows on this sensitive subject. WebA) Yes, since a force acts and the object moves, and work is force times distance. B) Yes, since it takes energy to turn an object. C) No, because the object has constant speed. D) No, because the force and the displacement of the object are perpendicular. D You throw a ball straight up. Compare the sign of the work done by gravity while the ball
Difference between electric field and electric force
http://physics.bu.edu/~duffy/py105/Energy.html WebIt is a single number without direction. Energy is zero if force and displacement stand in 90 degrees to each other. At the same time, torque is a vector defined as force X arm X sin( angle between them ). It points in a direction that has a 90 degree angle to both the arm and the force. Torque is zero if force and arm have the same direction. switch japanese
