CHAPTER 6 WORK AND ENERGY
... a. In both cases, the lift force L is perpendicular to the displacement of the plane, and, therefore, does no work. As shown in the drawing in the text, when the plane is in the dive, there is a component of the weight W that points in the direction of the displacement of the plane. When the plane i ...

Pre-notes across the bottom of home screen: Energy makes all
... This app explores several forms of energy with videos and fun facts. We will explore the major types of energy: potential energy and kinetic energy. Potential energy is stored energy that is ready to use. Kinetic energy is energy of motion. It is not just ready; it’s already on the move. We will als ...

We model static friction, Fstatic, with the inequality Fstatic s FN where s is the coefficient of static friction and FN the normal force exerted by a surface on the object. The normal force is defined as the perpendicular component o ...
