1. What is the Momentum Equation?

The momentum equation, \( p = m \times v \), calculates the momentum of an object, where p is momentum, m is mass, and v is velocity. It is a fundamental concept in physics that describes the quantity of motion an object has.

2. How Does the Calculator Work?

The calculator uses the momentum equation:

Where:

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

Explanation: The equation shows that momentum is directly proportional to both mass and velocity of an object.

3. Importance of Momentum Calculation

Details: Momentum is a conserved quantity in isolated systems, making it crucial for analyzing collisions and understanding motion in physics. It helps predict the outcomes of interactions between objects.

4. Using the Calculator

Tips: Enter mass in kilograms and velocity in meters per second. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What are the units of momentum?
A: Momentum is measured in kilogram meters per second (kg·m/s).

Q2: Is momentum a vector or scalar quantity?
A: Momentum is a vector quantity, meaning it has both magnitude and direction.

Q3: How is momentum conserved in collisions?
A: In an isolated system, the total momentum before collision equals the total momentum after collision.

Q4: What's the difference between momentum and kinetic energy?
A: Momentum depends on mass and velocity (\( m \times v \)), while kinetic energy depends on mass and velocity squared (\( \frac{1}{2}mv^2 \)).

Q5: Can momentum be negative?
A: Yes, since velocity can be negative (indicating direction), momentum can also be negative.
