Defining Force - Physics - Socratic
Jul 7, 2014 · A force is any influence which changes the motion of an object. There are two categories of forces: contact forces (when the two interacting objects physically contact each other, such as frictional, tension or normal forces), and forces resulting from action-at-a-distance (when the two interacting objects are not in physical contact with each other, such as the gravitational, electrical or ...
What are field forces in physics? + Example - Socratic
Mar 6, 2018 · When a body exerts an influence into the space around itself, we say that the body creates a " field " around itself. I tried to look up "field forces" but found nothing related to Physics given that phrase. I will assume you mean "force fields". When a body exerts an influence into the space around itself, we say that the body creates a " field " …
Electric Force - Physics - Socratic
An electric force is the attractive or repulsive interaction between any two charged objects. Like any force, its affect upon objects is described by Newton's laws of motion. We find electric force at work in anything that runs on batteries or uses a plug.
Frictional Forces - Physics - Socratic
Whenever an object moves against another object, it feels a frictional force which acts in the opposite direction to the movement. Friction makes it harder for things to move. It depends on the texture of both surfaces: frictional forces are much smaller on smooth surfaces than on rough surfaces, which is why we slide on ice. And it also depends on the force which presses the surfaces together ...
Magnetic Force - Physics - Socratic
Apr 26, 2014 · A magnetic force is the attraction or repulsion that arises between electrically charged particles because of their motion; the basic force responsible for the action of electric motors and the attraction of magnets for iron. Electric forces exist among stationary electric charges; and both electric and magnetic forces exist among moving electric charges. This force is usually measured in ...
What is the formula for average force? - Socratic
Feb 21, 2018 · Well, the net force is given by Newton's second law of motion, which states that F_"net"=ma where F_"net" is the force measured in newtons (N) m is the mass of the object in "kg" a is the acceleration of the object in "m/s"^2 Note that you can find the acceleration by differentiating the velocity of the object, if it's a function, like v(x), i ...
What is the difference between force and energy? | Socratic
Dec 21, 2017 · Force is related to energy, force x distance is energy transferred because 1 N x 1 m = 1 Nm If a force moves something work is done, that’s just another way of saying energy is being transferred. Indeed every energy transfer is accompanied by some force, that’s often the bit we “see” (not in atomic processes, but otherwise true.) So E …
Newton's Third Law - Physics - Socratic
Newton's third law states that when a body exerts a force on a second body, the second one simultaneously exerts a force equal in magnitude and opposite in direction to that of the first body. That is to say that whenever an object pushes another object, this one it gets pushed back in the opposite direction equally hard. For instance, a rocket's action is …
Work - Physics - Socratic
Work is done when a force that is applied to an object moves that object. There are three key ingredients to work - force, displacement, and cause. In order for a force to qualify as having done work on an object, there must be a displacement and the force must cause the displacement. Work is calculated by multiplying the force by the amount of movement of an object (W = F * d). Thus, a force ...
