examples and situation applied applied to newtons's law

Imagine the following situation. A heavy crate is resting on the floor in a warehouse. You push it horizontally with a steady force, but it does not move. That is because the force that you apply is balanced by a frictional force exerted horizontally on the bottom of the crate b..

Newton's Second Law of Motion - Newton's second law of motion states that rate of change of momentum is directly proportional to applied force and takes place in the same direction as the applied for..

Newton's second law of motion states that rate of change of momentum is directly proportional to applied force and takes place in the same direction as the applied forc..

The rate of change of momentum of a body is proportional to the applied force and takes place in the direction in which the force is applied..

Newton's Second Law of Motion - The rate of change of momentum of a body is proportional to the applied force and takes place in the direction in which the force is applied. For a constant mass system We have already learnt that the rate of change of velocity..

Newton's Second Law of Motion - Earlier we have mentioned that application of force can change the velocity of the moving object. Let us suppose that a body of mass 'm' is moving with a velocity 'u'. When a force F is applied on the body for 't' seconds, the velocity c..

Every body continues in its state of rest or of uniform motion in a straight line unless compelled by some external force to act otherwise. It is a matter of common experience that objects at rest do not begin to move of their own accord. If we place an object in a certain place we expect it to rem..

The emf of a cell is positive when one moves in the direction of increasing potential (i.e., negative pole to positive pole) through the cell and is negative when one moves from positive to negativ..

Applications of Newton's Second Law of Motion - In a cricket match a fielder moves his arms back while trying to catch a cricket ball because if he tries to stop the fast moving ball suddenly then the speed decreases to zero in a very short time. Therefore the retardation of the..

When we apply the force the door turns on its hinges. Thus a turning effect is produced when we try to open the door. Have you ever tried to do so by applying the force near the hinge? In the first case, we are able to open the door with ease. In the second case, we have to ..
