What is a Force What is Net Force Calculating Net Force Balanced in addition to Unbalanced Forces
Rodriguez, Mahelda, Executive Producer has reference to this Academic Journal, PHwiki organized this Journal What is a Force A as long as ce is a push or pull A as long as ce gives energy to an object, sometimes causing it to start moving (inertia), stop moving, or change direction. A spring scale is used to measure as long as ce. The unit of as long as ces is a Newton (N) What is Net Force Usually, more than one as long as ce is acting on an object. The net as long as ce is the combination of all the as long as ces acting on an object. Calculating Net Force Forces applied in the same direction are ADDED together.

Forces applied in opposite directions are SUBTRACTED. (The smaller as long as ce is subtracted from larger as long as ce in addition to direction of larger as long as ce is used) Balanced in addition to Unbalanced Forces When an object is not in motion, the as long as ces are balanced (the as long as ces acting on it are equal in all directions; a net as long as ce of 0 N) When an object is in motion, there are unbalanced as long as ces acting on it ( as long as ce in at least one direction is not the same as others). (A net as long as ce is not 0 N) Two types of Forces 1. Gravitational as long as ce of attraction between two objects; its dependent on the mass of the objects in addition to the distance between them. The greater the mass of an object, the greater its as long as ce of gravity will be As the distance between two objects increases, the gravitational as long as ce decreases
Two types of Forces, continued 2. Frictionala as long as ce that acts in the opposite direction of motion; friction must be overcome by a as long as ce. 3 Types of friction Slidingsolid objects slide over each other For example, sliding down park slide Rolling frictionthe use of wheels or bearings results in rolling friction. It is a lesser as long as ce than sliding friction. For example, roller blading on street
Fluid frictiongases in addition to liquids offer resistance to moving objects. This is also a lesser as long as ce than sliding friction. For example, swimming in ocean or racecar drivingair pushes against car
