Momentum Equation:
From: | To: |
The momentum equation (p = m × v) calculates the quantity of motion of a moving object, where p represents momentum, m represents mass, and v represents velocity. Momentum is a vector quantity with both magnitude and direction.
The calculator uses the momentum equation:
Where:
Explanation: The momentum of an object is directly proportional to both its mass and velocity. Doubling either mass or velocity will double the momentum.
Details: Momentum calculations are fundamental in physics for understanding collisions, conservation of momentum, rocket propulsion, and analyzing motion in various mechanical systems.
Tips: Enter mass in kilograms and velocity in meters per second. Both values must be positive numbers greater than zero.
Q1: What are the SI units for momentum?
A: The SI unit for momentum is kilogram-meter per second (kg·m/s).
Q2: Is momentum a scalar or vector quantity?
A: Momentum is a vector quantity, meaning it has both magnitude and direction.
Q3: What is the 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.
Q4: How does momentum relate to force?
A: Force equals the rate of change of momentum (F = Δp/Δt), as described by Newton's second law of motion.
Q5: Can momentum be negative?
A: Yes, momentum can be negative when the velocity vector points in the negative direction of the chosen coordinate system.
