Newton's First Law
A body will remain at rest or in motion at a constant velocity unless acted upon by a non-zero resultant force.
Newton's Second Law
Newton's Second Law
When a net force acts on an object, it accelerates in the direction of the net force. Acceleration is directly proportional to the force and inversely proportional to the mass.

Study Notes
- Physics Study Notes
Newton's First Law
- A body will remain in its state of rest or motion at a constant velocity unless a non-zero resultant force acts on it.
Newton's Second Law
- When a net force acts on an object, the object will accelerate in the direction of the net force.
- The acceleration is directly proportional to the force and inversely proportional to the mass of the object.
Newton's Third Law
- When object A exerts a force on object B, object B simultaneously exerts a force of equal magnitude on object A.
Newton's Law of Gravitation
- Each particle in the universe attracts every other particle in the universe with a gravitational force.
- The gravitational force is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
Momentum
- The product of an object's mass and its velocity.
Mass
- The numerical measure of inertia of an object.
Inertia
- The reluctance of an object to change its state of rest or motion.
Newton's Second Law (Momentum)
- The net force of an object equals the rate of change of momentum in the direction of the net force.
Impulse
- The product of the net force acting on an object and the time the net force acts on the object.
Principle of Conservation of Momentum
- Total linear momentum in an isolated system remains constant.
Isolated System
- No external forces act on the system.
Elastic Collision
- A collision in which the total kinetic energy is conserved.
Inelastic Collision
- A collision in which the total kinetic energy is not conserved.
