1. What is Momentum?

Momentum is a measurement involving the motion of an object in motion and the mass of the object. It is a vector quantity, possessing both magnitude and direction.

2. How Does the Calculator Work?

The calculator uses the momentum equation:

Where:

• \( p \) — Momentum (kg·m/s)
• \( m \) — Mass (kg)
• \( v \) — Velocity (m/s)

Explanation: The momentum of an object is directly proportional to both its mass and velocity.

3. Importance of Momentum Calculation

Details: Momentum is fundamental in physics, particularly in understanding collisions, conservation laws, and motion of objects.

4. Using the Calculator

Tips: Enter mass in kilograms and velocity in meters per second. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What are the units of momentum?
A: In the SI system, momentum is measured in kilogram-meters per second (kg·m/s).

Q2: How is momentum different from velocity?
A: Velocity measures speed with direction, while momentum incorporates both the object's mass and its velocity.

Q3: What is the principle of conservation of momentum?
A: In a closed system with no external forces, the total momentum remains constant before and after a collision.

Q4: Can momentum be negative?
A: Yes, momentum can be negative as it's a vector quantity - the negative sign indicates direction opposite to the defined positive direction.

Q5: How does momentum relate to force?
A: Force equals the rate of change of momentum (Newton's Second Law: F = dp/dt).
