Force Formula:
From: | To: |
Definition: This calculator determines the force required to change an object's velocity over a specific time interval.
Purpose: It helps physicists, engineers, and students understand the relationship between force, mass, and velocity change.
The calculator uses Newton's Second Law of Motion:
Where:
Explanation: The force equals mass multiplied by the rate of change of velocity (acceleration).
Details: Understanding this relationship is crucial for designing vehicles, safety systems, and any application involving motion.
Tips: Enter the mass in kg, velocity change in m/s, and time interval in seconds. Time must be > 0.
Q1: What if the velocity decreases?
A: Use a negative Δv value for deceleration. The force will be negative, indicating opposite direction.
Q2: How does mass affect the force?
A: Greater mass requires more force for the same acceleration. Force is directly proportional to mass.
Q3: What units should I use?
A: Use kg for mass, m/s for velocity, and s for time to get force in Newtons (N).
Q4: Can this calculate instantaneous force?
A: This gives average force over Δt. For instantaneous force, calculus (derivative) is needed.
Q5: How does this relate to momentum?
A: Force equals the rate of change of momentum (F = dp/dt), where p = mv.
