So far, we have come across first and second law of motion. In first law of motion, we learnt that every object tends to remain in its state of motion, until an external force is compelled to change the state. In second low of motion, we described that the rate of change of momentum of […]

As we discussed in previous blog, the first law of motion indicates that when an unbalanced external force acts on an object, its velocity changes, that is, the object gets an acceleration. From our everyday life observation, we know that, during the game of table tennis if the ball hits a player, it does not
Second Law of Motion and Momentum Read More »
We have observed that, if we put an object in motion it comes in state of rest. But if we put any object in state of rest it remains in that state. For example, if we throw a ball upward or roll it on the ground, it will ultimately come in the state of rest,
First Law of Motion and Inertia Read More »
From many centuries the problem of motion and its causes had puzzled scientists and philosophers until Galileo and Newton developed entirely different approach to understand motion. We have observed that, whenever an object is in motion it involves a form of hit, push or pull. In physics, a force is defined as any interaction such
Circular Motion is defined as the movement of an object along circumference of a circle. Some examples of circular motion are motion of moon around the earth, motion of a satellite in a circular orbit around the earth and motion of a cyclist on a circular tract etc. In last episode, we talked about acceleration. We
Before starting the topic, we need to understand that, there are two kinds of motion, we mentioned in our previous blog, known as Uniform Motion and non-uniform Motion. Let’s suppose, a car is moving on a road. It covered 5 m distance in 1 second, 5 m in next one second and again 5 m
Rate of Change of Motion Read More »
We have observed moving objects around us. From the observation we know that some objects move faster than other and some slower. For example, a man walks slower than a biker and a train run faster than a bike. In physics, there are two ways to measure the motion known as; Speed and Velocity. To
