Is the force exerted by the table on the statue the reactionto the weight of the statue? No, it is not. Both these forces Recall that the weight of the statue is the force with which the Earth attracts the statue. The reaction force is the force with which the statue attracts the Earth.Then what about the reaction force to the force exerted by the table? Because the statue and the table are in contact,
Friction forces arise when objects rub against each other. Friction acts parallel to the surface and opposes motion. Even though friction opposes motion, it doesn't always play a negative role. Without friction, all forms of surface transport including walking and running will be impossible. Experiments show that there are two types of friction forces: · Static friction · Kinetic friction Let's look at each one of them. Static Friction It is a common experience that if a heavy object such as a crate is pulled or pushed, the object does not begin to move unless the force applied reaches a critical value. Below this
