Learn Newton's Laws of Motion with interactive simulations and visualizations. Understand inertia, force, acceleration, and action-reaction pairs through hands-on examples.
Newton's laws of motion are three fundamental principles that describe the relationship between the motion of an object and the forces acting on it. These laws laid the foundation for classical mechanics and are essential for understanding how objects move and interact.
Law of Inertia
F = ma
Action-Reaction
An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
This law states that objects naturally resist changes in their state of motion. This resistance is called inertia. The greater the mass of an object, the greater its inertia.
The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
F = ma
This law quantifies the relationship between force, mass, and acceleration. When a net force acts on an object, it accelerates in the direction of the force. The acceleration is greater for larger forces and smaller masses.
For every action, there is an equal and opposite reaction.
This law states that forces always occur in pairs. When object A exerts a force on object B, object B simultaneously exerts an equal and opposite force on object A. These forces act on different objects.
Seat belts and airbags utilize Newton's laws to protect passengers during collisions by managing inertia and forces.
Rockets operate on Newton's third law by expelling gases to generate thrust for propulsion in vacuum.
Athletes optimize their techniques by applying Newton's laws to maximize performance and minimize injury.
