1. What Is Change In Momentum?

Change in momentum (Δp) represents the difference in an object's momentum between two points in time. It is a vector quantity that describes how much and in what direction an object's motion has changed, calculated as the product of mass and change in velocity.

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 formula shows that change in momentum is directly proportional to both the object's mass and the change in its velocity.

3. Importance Of Momentum Calculation

Details: Calculating change in momentum is fundamental in physics for understanding collisions, impulse, and conservation of momentum. It's essential in engineering applications, sports science, and vehicle safety design.

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

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

Q3: Does direction matter in momentum change?
A: Yes, momentum is a vector quantity, so both magnitude and direction are important in momentum change calculations.

Q4: What is impulse in relation to momentum change?
A: Impulse is equal to the change in momentum (J = Δp) and is calculated as force multiplied by time.

Q5: Can momentum change be negative?
A: Yes, momentum change can be negative, indicating a decrease in momentum or a change in the opposite direction.
