Newton's Second Law:
| From: | To: |
Newton's Second Law of Motion states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This fundamental principle forms the basis for classical mechanics and describes the relationship between force, mass, and acceleration.
The calculator uses Newton's second law equation:
Where:
Explanation: The equation shows that acceleration increases with greater force and decreases with greater mass. This linear relationship is fundamental to understanding motion dynamics.
Details: Calculating acceleration is essential in physics, engineering, automotive design, aerospace, and many other fields. It helps predict how objects will move under various forces and is crucial for safety calculations, vehicle performance analysis, and mechanical system design.
Tips: Enter force in newtons and mass in kilograms. Both values must be positive numbers greater than zero. The calculator will compute the resulting acceleration in meters per second squared.
Q1: What if the force is zero?
A: If the net force is zero, the acceleration will be zero according to Newton's first law (object at rest stays at rest, object in motion stays in motion).
Q2: Does this work for all types of motion?
A: This equation applies to linear motion. For rotational motion, different equations involving torque and moment of inertia are used.
Q3: What units should I use?
A: Use newtons for force and kilograms for mass to get acceleration in m/s². Ensure consistent units throughout the calculation.
Q4: How does this relate to gravity?
A: The acceleration due to gravity (g = 9.8 m/s²) is a specific case where F = mg, with F being the weight force.
Q5: Can this be used for multiple forces?
A: Yes, but you must first calculate the net force (vector sum of all forces) acting on the object before applying the formula.
