1. What is Linear Momentum?

Linear momentum is a fundamental quantity in physics that describes the motion of an object. It is defined as the product of an object's mass and its velocity, and is a vector quantity with both magnitude and direction.

2. How Does the Calculator Work?

The calculator uses the linear momentum equation:

Where:

• \( p \) — Linear momentum (kg·m/s)
• \( m \) — Mass of the object (kg)
• \( v \) — Velocity of the object (m/s)

Explanation: The momentum calculation shows how much "oomph" an object has when moving. In collisions, momentum is conserved, making it a crucial concept in physics.

3. Importance of Momentum Calculation

Details: Momentum calculations are essential for understanding collisions, explosions, and other interactions between objects. It's a conserved quantity in isolated systems, making it fundamental to physics problem-solving.

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 principle of conservation of momentum?
A: In an isolated system, the total momentum before a collision equals the total momentum after the collision.

Q2: How is momentum different from velocity?
A: Velocity describes speed and direction, while momentum incorporates both velocity and mass, giving a more complete description of motion.

Q3: What are elastic and inelastic collisions?
A: Elastic collisions conserve both momentum and kinetic energy, while inelastic collisions conserve momentum but not kinetic energy.

Q4: Can momentum be negative?
A: Yes, momentum can be negative as it's a vector quantity. Negative momentum indicates motion in the opposite direction of the defined positive direction.

Q5: How is impulse related to momentum?
A: Impulse equals the change in momentum. A force applied over time changes an object's momentum.
