1. What is the Mass Speed Formula?

Definition: This formula calculates the speed of an object based on its momentum and mass.

Purpose: It helps physicists and engineers determine an object's velocity when its momentum and mass are known.

2. How Does the Formula Work?

The formula is:

Where:

• \( v \) — Speed (meters/second)
• \( p \) — Momentum (kilogram meters/second)
• \( m \) — Mass (kilograms)

Explanation: The momentum is divided by the mass to determine the speed of the object.

3. Importance of the Mass Speed Formula

Details: This fundamental physics formula is essential for understanding motion, collisions, and dynamics in mechanical systems.

4. Using the Calculator

Tips: Enter the momentum in kg m/s and mass in kg. Both values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is momentum?
A: Momentum is a measurement involving the motion of a moving body, equal to the product of its mass and velocity.

Q2: What units should I use?
A: Use kg for mass, m/s for speed, and kg·m/s for momentum to maintain SI unit consistency.

Q3: Can this formula be used for relativistic speeds?
A: No, this classical formula is only accurate for speeds much less than the speed of light.

Q4: What if the mass is zero?
A: Mass cannot be zero in this calculation as it would require division by zero.

Q5: How is this different from kinetic energy?
A: Kinetic energy (½mv²) depends on speed squared, while momentum (mv) depends linearly on speed.
