Force And Motion - 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 mo..

In many cases when we pull or push an object, we find that force and displacement are not in the same direction. Let a constant force F acting on a body produce a displacement S as shown in the figure. Let q be the angle between the directions of th..

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 b..

Force - 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 te..

The first law of motion and inertia also applies to objects in motion. For example, When you pedal a bicycle, you accelerate to make the bicycle move forward. Because the forces acting on the bicycle are balanced, the bicycle and the rider keep..

Example of Balanced Forces Squeeze a rubber ball between the palms of your hands. What do you observe? The shape of the rubber ball changes. The forces applied on the ball are equal and opposite and the resultant of these forces does not move the objecth..

Thus the quantity of motion in a body depends on mass and velocity of the body. This quantity of motion defines a new physical quantity called momentum. The momentum of an object is defined as the product of its mass and its velocity. Momentum is a vector quantity ..

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..
