Types of Forces
... As mentioned above, the friction force is the force exerted by a surface as an object moves across it or makes an effort to move across it. For the purpose of our study of physics at The Physics Classroom, there are two types of friction force static friction and sliding friction. Sliding friction r ...

... In order to apply all we have learned to object of finite size, we need to define the center of mass (com). The center of mass (com) of a system of particles is the position through all external forces appear to act. It is the position we give an extended object. In practice it is the point around w ...

1 Mechanical Equilibrium
... A force is needed to change an object’s state of motion. The downward force acting on an object is called weight, while any stretching force on an object (such as a force exerted by a rope or wire) is called tension. The SI (Système International) unit for force is the newton (N). A newton weighs ab ...

The shape of the hill is approximately circular, with a radius of 60 m, as in the figure at right. When the car is at the highest point of the hill, a. What is the force of gravity on the car? b. What ...
