forces & motion

Pushes or Pulls are very general names given to forces. A physicist is much more precise when describing forces acting on a body using terms like weight, frictional force, tension, normal reaction force, electrical force, magnetic force..

Force - A force is often defined as a "push" or a "pull". There is nothing untrue with this statement, but does not really tell you much about a force. Instead of defining force, it substitutes an antonym. A physicist prefers to define a force in te..

Is the push/pull which changes or tends to change the state of rest or uniform motion in a straight line. It is a vector quantity, i.e., it has both magnitude and directio..

When two wet glass plates are pressed together, they cannot be separated easily. This is because of the force of attraction existing between the atoms and molecules, and are electrical in origin. As the two isolated Hydrogen atoms approach each other, the nucleus of one atom attracts the ..

Resultant Force - Any object can be made to move by the application of force. Many forces can act simultaneously on a body. For example, several people can jointly move a boulder but a strong person can move the same boulder all by himself. That is, the force..

An electric charge moving in a magnetic field experiences a force. This is called electromagnetic force. It is a combination of electricity and magnetism..

Force of Friction - According to Newton's first law of motion every body continues to be in its state of rest or uniform motion along a straight line unless an external force acts on it. This means that a ball moving on a horizontal surface should continue to move indefinitely a..
