newton’s law of motion

Newton’s first law. It states that an object at rest stays at rest, and an object in motion stays in motion with the same speed and direction unless acted upon by an unbalanced force.

Law of inertia

It states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass

Law of acceleration

The tendency of an object to resist changes in motion. The more the mass an object has, the more inertia it has.

Inertia

The Third law in Newton’s law of motion. It states that for every action, there is an equal and opposite action.

Law of Action and reaction

The ancient Greek philosopher who believed that force was required to keep an object in motion and that heavier objects fall faster than light ones

Aristotle

The scientist often credited with first describing the concept of inertia and arguing that all objects falls at the same rate regardless of mass (in a vaccum)

Galileo galilei

The 1687 publication by Isaac Newton that laid the groundwork for classical mechanics and described the three laws of motion

Philisopiæ naturalis principia mathematics

The era during the 16th and 17th centuries characterized by developments in mathematics, physics, and astronomy, which shifted the world away from Aristotelian views.

The Scientific revolution

The unit of force named in honor of the scientists who formulated the laws of universal gravitation and motion

Newton (N)
