5 Questions
According to Newton's first law of motion, what happens to a body unless acted upon by a force?
Remains at rest or in motion at a constant speed in a straight line
What is the relationship between a body's acceleration, mass, and net force according to Newton's second law of motion?
Acceleration multiplied by mass equals the net force
What is the characteristic of the forces exerted by two bodies on each other according to Newton's third law of motion?
Forces have the same magnitude but opposite directions
In which publication did Isaac Newton first state the three laws of motion?
Philosophiæ Naturalis Principia Mathematica
What are the limitations to Newton's laws of motion?
New theories are necessary when objects move at very high speeds, are very massive, or are very small
Study Notes
Newton's Laws of Motion
- A body remains at rest or continues to move with constant velocity unless acted upon by a net external force, according to Newton's first law of motion.
- The acceleration of a body is directly proportional to the net force acting on it and inversely proportional to its mass, as stated by Newton's second law of motion (F = ma).
- The forces exerted by two bodies on each other are equal in magnitude and opposite in direction, known as the law of action and reaction, according to Newton's third law of motion.
- Isaac Newton first presented the three laws of motion in his publication "Philosophiæ Naturalis Principia Mathematica" in 1687.
- Newton's laws of motion are limited to describing the motion of objects at low speeds, in the absence of strong gravitational fields, and do not account for relativistic effects or quantum mechanics.
