Newton's Laws of Motion are foundational principles that describe the behavior of objects in motion and the forces acting upon them. The First Law, or Law of Inertia, states that an object will remain at rest or in uniform motion unless acted upon by an external force. The Second Law relates force, mass, and acceleration with the equation F=ma. The Third Law asserts that every action has an equal and opposite reaction. Additionally, Newton's Law of Universal Gravitation explains the gravitational attraction between masses.

Objects will remain at rest or in motion unless acted upon by an external force
The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass
For every action, there is an equal and opposite reaction
The tendency of an object to resist changes in its state of motion
The greater the mass of an object, the greater its inertia and the more force required to alter its motion
The acceleration of an object is directly proportional to the net external force acting on it and inversely proportional to its mass, expressed by the equation F=ma
Used to calculate the force needed to push a heavy object or determine the acceleration of a car
For every force exerted by one object on another, there is an equal and opposite force exerted by the second object on the first
Demonstrated in actions such as the recoil of a gun or the force exerted by a swimmer's hands on the water
The force of attraction between two masses, described by the equation F = G (m1m2/r^2)
Explains the orbits of celestial bodies, tides on Earth, and the behavior of objects under the influence of gravity

Continues to be a fundamental principle in fields such as transportation, space travel, and technology development
00
Newton's First Law - Law of Inertia
Objects remain at rest or move at constant velocity unless acted upon by external force.
01
Newton's Second Law - Force, Mass, and Acceleration
Acceleration of an object is proportional to net force and inversely proportional to mass (F=ma).
02
Newton's Third Law - Action and Reaction
For every action, there is an equal and opposite reaction, indicating forces act in pairs.
