1. What is Momentum After Collision?

Momentum after collision refers to the product of an object's mass and its velocity following a collision event. It is a fundamental concept in physics that helps describe the motion of objects after they interact.

2. How Does the Calculator Work?

The calculator uses the momentum formula:

Where:

• \( p_{\text{after}} \) — Momentum after collision (kg·m/s)
• \( m \) — Mass of the object (kg)
• \( v_{\text{after}} \) — Velocity after collision (m/s)

Explanation: The momentum calculation is straightforward - it's simply the product of mass and post-collision velocity.

3. Importance of Momentum Calculation

Details: Calculating momentum after collision is essential for understanding energy conservation, analyzing collision outcomes, and predicting object behavior in various physics applications.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What is the unit of momentum?
A: Momentum is measured in kilogram-meters per second (kg·m/s).

Q2: How is momentum conserved in collisions?
A: In closed systems, the total momentum before collision equals the total momentum after collision (conservation of momentum).

Q3: What's the difference between elastic and inelastic collisions?
A: In elastic collisions, both momentum and kinetic energy are conserved. In inelastic collisions, only momentum is conserved.

Q4: Can momentum be negative?
A: Yes, momentum can be negative if the velocity is in the opposite direction of the chosen positive direction.

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