external forces for change

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..

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 terms of what it doe..

A vegetable vendor applies force to push the cart, a driver applies force either to stop the car or to change the speed or direction of motion and a football player kicks the ball to set it in motion. In all the above examples, the force applied on a body can..

Force is the external agent that changes the state of rest or uniform motion of a body along a straight lin..

Elasticity and Deforming Forces - External forces acting on a body, bring about a change in its state or configuration. The latter is possible when the body is not free to move, but the molecules are compelled to change their positions. Such fo..

Dipole in an external field Consider a permanent dipole of dipole moment 'p' in a uniform external field E, which implies that p does not depend E nor it is induced due to E. The force on q is qE and on -q is -qE and net force on dipole is zero. H..

Question 1 - Question: Define force. Answer: Force is an external agent or influence, which changes or tends to change the state of rest or state of uniform motion of a body in a straight lin..

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 as no force..

Introduction - 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 ..

Drop a stone from a height. What do you observe? The stone which was initially at rest starts moving towards the ground and attains a maximum speed just before it touches the ground. The stone is not moving with uniform speed. Its speed keeps changing at every instant, which means that th..
