1. What is the Momentum Equation?

Definition: The momentum equation relates an object's mass and velocity to its momentum.

Purpose: It helps in understanding and calculating the quantity of motion of an object.

2. How Does the Equation Work?

The equation is:

Where:

• \( p \) — Momentum (kg m/s)
• \( m \) — Mass of the object (kg)
• \( v \) — Velocity of the object (m/s)

Explanation: Momentum is directly proportional to both mass and velocity of an object.

3. Importance of Momentum Calculation

Details: Momentum is a fundamental concept in physics, crucial for understanding collisions, motion, and force.

4. Using the Calculator

Tips: Enter the 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: The SI unit for momentum is kilogram meters per second (kg m/s).

Q2: How does momentum relate to force?
A: Force equals the rate of change of momentum (F = Δp/Δt).

Q3: What's the difference between momentum and velocity?
A: Velocity is speed with direction, while momentum includes both mass and velocity.

Q4: Can momentum be negative?
A: Yes, momentum can be negative when velocity is negative (indicating opposite direction).

Q5: What is conservation of momentum?
A: In a closed system without external forces, total momentum remains constant.
