Velocity Formula:
From: | To: |
Definition: Velocity is a vector quantity that refers to the rate at which an object changes its position.
Purpose: It helps in understanding motion by describing both the speed and direction of an object's movement.
The calculator uses the formula:
Where:
Explanation: The distance covered is divided by the time taken to cover that distance, giving the average velocity.
Details: Velocity is fundamental in physics for analyzing motion, calculating trajectories, and solving problems in mechanics.
Tips: Enter the distance in meters and time in seconds. Both values must be > 0. The result will be in meters per second (m/s).
Q1: What's the difference between speed and velocity?
A: Speed is scalar (magnitude only) while velocity is vector (magnitude and direction).
Q2: Can velocity be negative?
A: Yes, negative velocity indicates motion in the opposite direction of the reference point.
Q3: What units should I use?
A: The calculator uses meters and seconds, but you can convert from other units before entering values.
Q4: How is this different from average velocity?
A: This calculates average velocity over the entire distance and time period.
Q5: What if I need instantaneous velocity?
A: Instantaneous velocity requires calculus (derivative of position with respect to time).
