Total Momentum Formula:
From: | To: |
Total momentum is the sum of the momentum of all objects in a system. Momentum is a vector quantity defined as the product of an object's mass and velocity, representing the quantity of motion it possesses.
The calculator uses the momentum formula:
Where:
Explanation: For multiple objects, the total momentum is the vector sum of individual momenta. This calculator computes momentum for a single object.
Details: Momentum calculation is fundamental in physics for analyzing collisions, understanding conservation laws, and predicting motion in mechanical systems.
Tips: Enter mass in kilograms and velocity in meters per second. Both values must be valid (mass > 0).
Q1: Is momentum a scalar or vector quantity?
A: Momentum is a vector quantity, meaning it has both magnitude and direction.
Q2: 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 collisions or interactions.
Q3: 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.
Q4: What are typical units for momentum?
A: The SI unit is kilogram-meter per second (kg·m/s). Other units include g·cm/s or slug·ft/s.
Q5: How is momentum different from kinetic energy?
A: Momentum depends on mass and velocity (p = mv), while kinetic energy depends on mass and velocity squared (KE = ½mv²). Momentum is conserved in all collisions, while kinetic energy is only conserved in elastic collisions.
