1. What Is Change In Momentum?

Change in momentum (Δp) is a fundamental concept in physics that represents the difference in an object's momentum between two points in time. It is calculated as the product of an object's mass and its change in velocity.

2. How Does The Calculator Work?

The calculator uses the momentum change equation:

Where:

• \( \Delta p \) — Change in momentum (kg·m/s)
• \( m \) — Mass of the object (kg)
• \( \Delta v \) — Change in velocity (m/s)

Explanation: This equation shows that the change in momentum is directly proportional to both the mass of the object and the change in its velocity.

3. Importance Of Momentum Calculation

Details: Calculating change in momentum is essential in physics for understanding collisions, impulse, and conservation of momentum. It's widely used in engineering, sports science, and accident reconstruction.

4. Using The Calculator

Tips: Enter mass in kilograms and velocity change in meters per second. Both values must be valid (mass > 0).

5. Frequently Asked Questions (FAQ)

Q1: What is the SI unit for momentum?
A: The SI unit for momentum is kilogram-meter per second (kg·m/s).

Q2: How is momentum related to force?
A: According to Newton's second law, force equals the rate of change of momentum (F = Δp/Δt).

Q3: What is the principle of conservation of momentum?
A: In a closed system with no external forces, the total momentum before a collision equals the total momentum after the collision.

Q4: Can momentum be negative?
A: Yes, momentum is a vector quantity, so it can be negative depending on the direction of motion.

Q5: How does mass affect momentum?
A: Momentum is directly proportional to mass - heavier objects have greater momentum at the same velocity.
