Forces and Motion
... The force that one surface exerts on another when the two surfaces rub against each other. The tendency of an object to resist any change in its motion. The force that pulls objects toward each other. ...

What are forces?
... A car is traveling at constant speed. Is a force acting on it? Answer: although there are forces acting on the car (gravity, friction, air resistance,etc…) since there is no acceleration, the net force in the direction of motion must be zero. ...

... Aristotle (384-322BC): A natural state of a body is rest. Thus force is required to move an object. To move faster, ones needs larger forces. Galileo’s statement on natural states of matter: Any velocity once imparted to a moving body will be rigidly maintained as long as the external causes of reta ...

... (a) Only an inward force is required for circular motion at constant speed. One might think that a forward force would be needed in order to maintain the forward motion, but that’s an Aristotelian preconception. Motion doesn’t naturally slow down. (b) The observers disagree on velocities, but they a ...

... Normal forces act in the vertical direction, then the Normal force and Weight are NO LONGER EQUAL. For instance, if we stood on the box, or if we attached a rope and pulled up slightly. In both these cases, the normal force must balance all other vertical forces so that the net vertical force = 0. ...
