The equation for determining the net force acting on an object is F = ma, or force equals mass times acceleration. Net force is measured in terms of acceleration, which means a change in velocity. If there is no change in velocity, the net force is considered to be zero.
At any time, there can be many forces acting upon an object, including gravity, friction and any external forces pushing or pulling on the object. The net effect of all of these forces is determined by the acceleration of the object. Acceleration is observed when a stationary object begins to move, a moving object changes speed or when an object in motion changes direction.Learn More
When a force is applied to an object resting on a surface, a retarding force is that which opposes the force being applied to the object. A retarding force is usually that of friction, which must be overcome when moving an object resting on a surface. If the object is being moved upward along an inclined plane, gravity represents an additional force that must be overcome.Full Answer >
Weight is the measure of the gravitational force on an object. Weight is related to mass but is actually a separate property. Weight and mass are often treated as interchangeable because gravity on Earth does not vary much based on location.Full Answer >
Solving for the electrostatic force requires the use of Coulomb's Law, which is shown in the following equation: F = K(q1*q2)/d^2. The electrostatic force is the force that two electric charges exert on one another. It is an important concept in the physics of electricity. This force is exerted by each charge on the other, the only difference is the direction.Full Answer >
Centripetal force refers to the force that makes objects move in circular paths. Centripetal force makes an object or body follow a curved path; the direction of the body moves towards the center or fixed point of the circular path.Full Answer >
