forces that can change price

A collision is said to take place when one body coming forcibly in contact with another or when the path of one body is changed by the influence of the other body. As a result of collision, the momentum and kinetic energy of the interacting bodies change. The forces in..

Simple Machines - In all the above examples, a machine either multiplies or reduces the effect of the force that is applied. A bicycle is a machine which is used to gain speed. We gain speed by exerting additional force. When we try to ride a bicycle up a steep hill, we soon rea..

According to Newton's second law of motion, force acting on a body is defined as the rate of change of its momentu..

All material bodies exhibit inability to change by themselves, their state of rest or of uniform motion in a straight line. This property is called inertia. Hence, a body at rest remains at rest and a body in motion continues to be in uniform motion in a straight line unless some externa..

Introduction - A spider web is stronger than steel of the same thickness. Its elastic limit is greater than that of steel. A force is a push or pull exerted by one object or body on another. It may cause a body at rest to move or one in motion, to change its speed or direction. ..

Fluids are substances which begin to flow when external force is applied on them. Liquids and gases are fluids. Fluids do not have a definite shape. The branch of physics, dealing with the study of fluids at rest is called hydrostatics. When fluids are kept in a container, due to random ..

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 changes from the initia..

Mass is the quantity of matter in the body. Mass is measured by finding out the force needed to change the way the object moves. The greater the force needed, greater the mass of the object. If you push a book, it moves faster than if you push a car with the same ..
