Force & Motion Calculator

Calculate force, mass, and acceleration using Newton's Second Law

Force (F = ma)

0.00 N

F = 1.00 kg × 0.00 m/s² = 0.00 N

Newton's Laws of Motion

First Law: An object at rest stays at rest, and an object in motion stays in motion unless acted upon by an external force.

Second Law: F = ma (Force equals mass times acceleration)

Third Law: For every action, there is an equal and opposite reaction.

About Force & Motion

Force and motion are fundamental concepts in physics that describe how objects interact with each other and how these interactions affect their movement. Newton's laws of motion provide the foundation for understanding these concepts.

Newton's Laws of Motion

Sir Isaac Newton formulated three laws that describe the relationship between a body and the forces acting upon it:

  • First Law (Law of Inertia): 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.
  • Second Law: The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F = ma).
  • Third Law: For every action, there is an equal and opposite reaction.

Types of Forces

There are several types of forces in physics, including:

  • Gravitational Force: The attraction between objects with mass.
  • Frictional Force: The resistance to motion when two surfaces are in contact.
  • Normal Force: The perpendicular force exerted by a surface on an object.
  • Tension: The force transmitted through a string, rope, or cable when pulled tight.
  • Applied Force: Any force that is applied to an object by another object or person.

Applications of Force & Motion

Understanding force and motion is crucial in many fields, including engineering, sports, transportation, and space exploration. Engineers design machines and structures based on these principles, athletes optimize their performance by applying forces effectively, and space agencies calculate the forces needed to launch and navigate spacecraft.
