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 describes the relationship between force, mass, and acceleration in classical mechanics.
The calculator uses Newton's Second Law equation:
Where:
Explanation: The equation shows that acceleration increases with greater force and decreases with greater mass, following a linear relationship.
Details: Calculating acceleration is essential in physics, engineering, and various applications including vehicle design, sports science, and space exploration. It helps predict motion and design systems that require specific acceleration profiles.
Tips: Enter net force in newtons (N) and mass in kilograms (kg). Both values must be positive numbers greater than zero. The calculator will compute the resulting acceleration in meters per second squared (m/s²).
Q1: What is the difference between net force and applied force?
A: Net force is the vector sum of all forces acting on an object, while applied force refers to a single force. The calculator requires net force for accurate acceleration calculation.
Q2: Can this calculator be used for objects in free fall?
A: Yes, for free fall near Earth's surface, the net force is weight (mg), so acceleration equals gravitational acceleration (approximately 9.8 m/s²).
Q3: What are typical acceleration values in everyday situations?
A: Car acceleration: 2-4 m/s², elevator: 1-2 m/s², free fall: 9.8 m/s², space shuttle launch: 20-30 m/s².
Q4: Does this equation work for all reference frames?
A: Newton's Second Law applies in inertial reference frames. For non-inertial frames, fictitious forces must be considered.
Q5: How does air resistance affect acceleration calculations?
A: Air resistance reduces net force, therefore decreasing acceleration. This calculator assumes ideal conditions without air resistance unless accounted for in the net force input.
