Newton is the first scientist who founded the physics of motion by stating five fundamental laws of physics.
Newton's First LawEdit
- Any object at rest or in uniform motion will remain at rest or in uniform motion unless an external force is applied to the object. .
Newton's Second LawEdit
- To change an object's state a Force must act on the object .Force is a quantity that acts on object to perform a task . For examples a pulling or pushing Force used to move the table . Force used to break a piece of wood
- To make an object accelerates, a force must act on the object. This force is found to be proportional to the object's mass and acceleration:
- F = m a
Newton's Third LawEdit
- When a force acts on an object, the object exerts an opposing force of equal magnitude but opposite direction to the force acting on the object.
- F = - f = - m a
Newton's Fourth LawEdit
- The net force acting on an object at rest or in equilibrium is zero .
Newton's Law of GravitationEdit
- The gravitational force of the Earth acts on any object above the earth is directly proportional to the mass of the Earth and the mass of the object and inversely proportional to the square of the distance between the Earth and the object.
