Velocity is a vector quantity that represents the rate of change of an object's position with respect to time. When momentum is known, velocity can be calculated by dividing momentum by the object's mass.
The calculator uses the formula:
Where:
Explanation: This formula directly relates an object's velocity to its momentum and mass, following from the definition of momentum as the product of mass and velocity.
Details: Calculating velocity from momentum is fundamental in physics for analyzing motion, solving dynamics problems, and understanding the relationship between an object's motion and its physical properties.
Tips: Enter momentum in kg·m/s and mass in kg. Both values must be positive (mass > 0). The calculator will compute the velocity in meters per second.
Q1: What is momentum?
A: Momentum is the product of an object's mass and velocity, representing the quantity of motion an object possesses.
Q2: Why is velocity a vector quantity?
A: Velocity has both magnitude (speed) and direction, making it a vector quantity that describes motion in specific spatial terms.
Q3: What are typical units for velocity?
A: The SI unit for velocity is meters per second (m/s), though other units like km/h or mph are also commonly used.
Q4: Can velocity be negative?
A: Yes, velocity can be negative when an object is moving in the opposite direction of the defined positive direction in a coordinate system.
Q5: How does mass affect velocity?
A: For a given momentum, a larger mass results in a lower velocity, and a smaller mass results in a higher velocity, as they are inversely proportional.
