PPT-NEWTON’S FIRST LAW OF MOTION

The Law of Inertia The first law says that an object at rest tends to stay at rest and an object in motion tends to stay in motion with the same direction and speed unless acted upon by an unbalanced force. 1.

Motion. Newton’s Third Law of Motion. Glossary. Inertia. is the property of objects that makes them resist changes in their motion. So, the greater the mass of an object, the more inertia it has. For example, it takes a much . Whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first.. “To every action there is an equal and opposite reaction”. F(AB) = - F(BA). nd. Law of Motion. Newton’s 2. nd. Law of Motion:. . acceleration of an object is in the same direction as the net force on the object. Newton’s 2. nd.

It is a universal force that causes all objects to pull on all other objects everywhere. Galileo’s work helped correct misconceptions about force and motion that had been widely held since Aristotle’s time. It took about 2000 years to develop the modern understanding of the relationships between force and motion.
