It is a well known story that Sir Newton was sitting under apple tree. He saw the apple falling on the ground. He thought about few things. First, since apple was present on the tree at rest, there should be no applied force at that time. When apple falls on ground, there should be a force to accelerate it. What is that force? Here came the concept of gravity. I like to share this Potential Energy Equation with you all through my article.

While studying about calculus and physics, Sir Isaac Newton came up with three laws of motion.

The first law of motion states that a resting object will remain in rest and a moving object will continue to move with constant velocity unless an unbalanced external force is applied to it. This is also known as law of inertia of object. It explains tendency of objects to resist change in their motion and to remain in state of inertia.

The second law of motion is about an object on which some external force is applied. Under these conditions, the change in acceleration or velocity of object is proportional to the amount to applied force and is indirectly proportional to its mass.

According to third law of motion, for each force, there is equal resulting force that operates in opposite direction. Please express your views of this topic Average Kinetic Energy by commenting on blog.

According to Newton’s law of gravity, each object on earth attracts every other object with a force. This force is known as force of gravity. The force of gravity is proportional to product of their masses and inversely proportional to the squares of distance between them.

The first law of motion can be understood by following example. Suppose a dish is lying on the floor. Here is no applied force on the dish. The only present force is force of friction. If we apply force on dish in the quantity to overcome the force of friction, the dish will start sliding on the floor. Now the change in velocity of the dish will be according to the amount of applied force.

The second law of motion can be explained by following example. Suppose a boy is asked to push two sacks, one weighing 10 kg and other 25 kg. The boy will need to apply more force on the heavier object to push it. This is in accordance to the second law of motion.

The third law can be explained by example of rocket launching. When a rocket is launched, rocket pushes the ground with a force. The opposite force pushes the rocket in upward direction.

Sir Newton came up with law of gravity that states that each object exerts force of gravity of other objects and gave laws of gravity.
