Newton’s Second Law states that the acceleration of an object depends inverse Ely on TTS mass and directly on the unbalanced force applied to it. To describe this la w, the proportionality AAA MFC is used. Further, we are able to derive the equation f net ma from this. F” represents an unbalanced force acting upon an object and its direction. ” m ” represents the mass of the object being acted upon and ” a ” is the acceleration, being the rate of change per unit of time ( ms Many forces may be acting on a single object but, by adding determined vectors, we are able to find the net force ( f net) causing motion.
In addition to unbalanced forces, the force of friction also affects the object. T his force s is dependent on the types of materials in contact and the normal force. It c an be represented mathematically through the equation f friction = p x f normal . Newton’s Third Law states that for every action force, there is an equal and opposite reaction force e. The reaction force between two objects is known as the Normal Force ( f normal) and is always perpendicular to the force causing contact between objects.

With greater mass, a greater No Irma Force is produced thus creating more friction. Further, materials behave differently w hen in contact due to attractions at the atomic level caused by irregularities and electromagnet ethic attraction, contributing to friction. The Greek letter” ” (um) is scalar value that represents this interaction, known as the Coefficient of Friction. Since it is simply the repress notation of a ratio f ( p = f NFG p has no unit value associated with it. P is used to represent two forms of friction: kinetic and static.
The Coefficient of Kinetic Friction is the relationship between n two objects, including one with a velocity. The Coefficient Of Static friction represents two objects in a state of rest. Commonly, the Coefficient of Kinetic Friction is lower due to the object’s initial motion. Both forms of friction use identical equations but must be used carefree Lully due to their two different representations. In this lab, we investigated the coefficient of static friction between a shoe an d a table by measuring the force needed to counteract the force of friction.
