1. What is the Velocity Equation?

The velocity equation (v = p/m) calculates the velocity of an object from its momentum and mass. This fundamental physics equation relates these three key mechanical properties.

2. How Does the Calculator Work?

The calculator uses the velocity equation:

Where:

• \( v \) — Velocity (m/s)
• \( p \) — Momentum (kg·m/s)
• \( m \) — Mass (kg)

Explanation: The equation shows that velocity is directly proportional to momentum and inversely proportional to mass.

3. Importance of Velocity Calculation

Details: Calculating velocity from momentum and mass is essential in physics, engineering, and various applications like vehicle dynamics, ballistics, and particle physics.

4. Using the Calculator

Tips: Enter momentum in kg·m/s and mass in kg. Both values must be positive numbers. The calculator will compute the velocity in meters per second (m/s).

5. Frequently Asked Questions (FAQ)

Q1: What are typical units for this calculation?
A: Standard SI units are kg·m/s for momentum, kg for mass, resulting in m/s for velocity.

Q2: Can this be used for relativistic velocities?
A: No, this classical formula is only accurate for velocities much smaller than the speed of light.

Q3: How does this relate to kinetic energy?
A: Kinetic energy can be calculated from velocity (KE = ½mv²) or from momentum (KE = p²/2m).

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

Q5: Can this be used for rotational motion?
A: For rotational motion, you would use angular velocity and angular momentum instead.
