Flashcards: MCAT Physics and Math 1.5: Newton's Laws
Newton's first law equation
Fnet = ma = 0
Newton's first law:
A body either at rest or in motion with constant velocity will remain that way unless a net force acts upon it.
Newton's first law is also known as the _____ and can be thought of as a special case of _____
law of inertia
Newton’s second law
Newton’s second law
An object of mass m will accelerate when the vector sum of the forces results in some nonzero resultant force vector.
The direction of the force vector and resultant acceleration are the same
Newton’s second law equation
Fnet = ma
Newton’s third law
To every action, there is always an opposed but equal reaction
More formally, the law states that for every force exerted by object A on object B, there is an equal but opposite force exerted by object B on object A.
