Newton`s Laws of Motion
... When you push your hands through the water, you are exerting a force on the water – the action force The reaction is the water pushing back on your hand You move forward in the water because your action force is stronger than the water’s reaction force ...

Motion of a charged particle in combined fields :-
... magnetic filed will set the electron in a circular motion. → The Radius of the circular path is independent of the elecric field, but the velocity along the field changes with time. As a result of this the elctron travels in a helical path with the pitch changing with time. ...

... Objects at rest tend to remain at rest unless a force is applied to set them in motion When an object is moving its tendency is to remain moving along a straight line path if no friction acts against it. ...

Uniform Circular Motion
... only if a force is exerted on it. Since an object moving with uniform circular motion is always accelerating, there must always be a force exerted on it in the same direction as the acceleration, as illustrated in Figure 11.7. If at any instant the force is withdrawn, the object will stop moving alo ...

Newton’s Laws of Motion
... Earlier, Aristotle said objects were “naturally” at rest, and needed a continuing push to keep moving. Galileo realized that motion at constant velocity is “natural”, and only changes in velocity require external causes. ...

... Static Friction: Push with a force F and block does not move because fs = F. The force of friction varies from 0 up to some maximum. The maximum value equals fs = msN, where N is the normal force. Above we would have fs = msmg. The coefficient of static friction ranges from 0 to 1.2 Kinetic Friction ...
