problems on laws of motion

In a lawn sprinkler when water sprays out of the nozzles, a backward force is exerted on the nozzle as a result of which it starts rotating. Consequently, water is sprayed in all directions. Consider a block of weight w resting on a horizontal surface. The block exerts a downward force of w on..

Introduction - The word force in common usage refers to a push or pull. The word Mass is also just as familiar as the word force. A super tanker is one that contains an enormous amount of mass. In comparison a coin does not contain much mas..

When a bullet is fired from a gun, the gases produced in the barrel exerts a tremendous force on the bullet (action force). As a result, the bullet moves forward with a great velocity called the muzzle velocit..

You have understood from Newton's first law that change in motion is caused due to an external force. We are now in a position to define for..

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 ball will be very large. As a result the fielder has to apply a lar..

Newton's Third Law of Motion and Force of Gravitation - Is Newton's third law of motion applicable to gravitational force? Yes it is. Let us now see how Newton's third law of motion is applicable to the gravitational force existing between..

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..

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 tim..

whenever a force is acting on an object, it produces acceleration in it. The gravitational force of attraction produces acceleration both in the Earth and in the ston..
