Momentum Formula:
From: | To: |
Momentum is a fundamental concept in physics that describes the quantity of motion an object has. It is a vector quantity, meaning it has both magnitude and direction, calculated as the product of an object's mass and velocity.
The calculator uses the momentum formula:
Where:
Explanation: Momentum increases with either greater mass or higher velocity, and it's conserved in isolated systems according to the law of conservation of momentum.
Details: Calculating momentum is essential in physics for understanding collisions, predicting motion outcomes, and analyzing various physical phenomena from particle physics to celestial mechanics.
Tips: Enter mass in kilograms and velocity in meters per second. Both values must be positive numbers.
Q1: Is momentum a vector or scalar quantity?
A: Momentum is a vector quantity, meaning it has both magnitude and direction.
Q2: What is the unit of momentum?
A: The SI unit for momentum is kilogram-meter per second (kg·m/s).
Q3: How is momentum different from velocity?
A: Velocity measures speed with direction, while momentum incorporates both velocity and mass, representing the quantity of motion.
Q4: What is the law of conservation of momentum?
A: In a closed system with no external forces, the total momentum before a collision equals the total momentum after the collision.
Q5: 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.
