1. What Is Change In Momentum?

Change in momentum (Δp) represents the difference in an object's momentum between two points in time. Momentum is a vector quantity that depends on both mass and velocity of an object.

2. How Does The Calculator Work?

The calculator uses the momentum change 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 equals the product of the object's mass and its change in velocity. This fundamental principle is derived from Newton's second law of motion.

3. Importance Of Momentum Calculation

Details: Calculating change in momentum is crucial in physics for understanding collisions, impulse, force applications, and conservation of momentum in closed systems.

4. Using The Calculator

Tips: Enter mass in kilograms and change in velocity in meters per second. Mass must be a positive value, while change in velocity can be positive or negative depending on direction.

5. Frequently Asked Questions (FAQ)

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

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

Q3: Can change in momentum be negative?
A: Yes, change in momentum can be negative if the object is slowing down or changing direction opposite to its initial motion.

Q4: What is impulse and how does it relate to momentum change?
A: Impulse is the product of force and time (J = FΔt), and it equals the change in momentum (J = Δp).

Q5: Is momentum conserved in all collisions?
A: Momentum is conserved in all closed systems where no external forces act, regardless of whether the collision is elastic or inelastic.
