1. What is the Change in Momentum Formula?

The change in momentum formula, Δp = m × Δv, calculates the change in an object's momentum based on its mass and change in velocity. Momentum is a vector quantity that describes the quantity of motion an object has.

2. How Does the Calculator Work?

The calculator uses the change in momentum formula:

Where:

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

Explanation: 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 fundamental in physics, particularly in understanding collisions, impulse, and conservation of momentum principles. It's essential for analyzing forces in dynamic systems.

4. Using the Calculator

Tips: Enter mass in kilograms and change in velocity in meters per second. Both values are required for calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is momentum in physics?
A: Momentum is the product of an object's mass and velocity, representing the quantity of motion it possesses.

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

Q3: What are the units of momentum?
A: Momentum is measured in kilogram-meters per second (kg·m/s) in the SI system.

Q4: Is momentum a vector or scalar quantity?
A: Momentum is a vector quantity, meaning it has both magnitude and direction.

Q5: 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.
