Newtons Laws Of Motion
Transcript of Newtons Laws Of Motion
This is represented as: F=ma where F is the force exerted, m is the mass of the body and a is the acceleration of the body. The first law is or states that an object at rest tends to stay at rest and an object in uniform motion stays in uniform motion until an external force is exerted on the object.
This is also called the law of Inertia.
This means that if a body is not moving or moving at a constant speed, in a straight line, will stay like that until a a force is exerted on the body. So,who is Newton? What are these laws of motion? Sir Issac Newton was a mathematician, astronomer, natural Philosopher, theologists, alchemist, and a physicist.
Some of his discoveries which I'm going to talk about are the principles or the laws of motion. This means that if a force is applied by a body on an object, then an equal and opposite force is applied by the object on the body.
For example, you are sitting on a chair, you exert a force which is equal to your weight on the chair, then the chair exerts an equal and opposite force on you. So now both the forces are canceled by each other and you and the body are in equilibrium. The third law states, For every action there is equal and opposite reaction. So...These are the Three Laws Of Motion....... Sir Isaac Newton
