Force Formula:
From: | To: |
Definition: This equation calculates the force required to change an object's velocity over time, based on Newton's Second Law of Motion.
Purpose: It helps physicists, engineers, and students determine the force needed to accelerate or decelerate an object.
The equation is expressed as:
Where:
Explanation: The force is directly proportional to the mass and 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 period in seconds. Time must be > 0.
Q1: What if velocity decreases (deceleration)?
A: Use a negative Δv value to calculate deceleration forces (braking forces).
Q2: How does mass affect the force?
A: Greater mass requires more force to achieve the same acceleration (directly proportional).
Q3: What units should I use?
A: Use kg for mass, m/s for velocity, and s for time to get Newtons (N) as the result.
Q4: Can this calculate impact forces?
A: Yes, if you know the velocity change during collision and the collision duration.
Q5: How is this related to acceleration?
A: Δv/Δt equals acceleration (a), so this is essentially F = ma in different form.
