How to Use the Calculator
- Enter the initial velocity (v₀) of the object in meters per second (m/s)
- Enter the final velocity (v) of the object in meters per second (m/s)
- Enter the time interval (Δt) during which the velocity changed in seconds (s)
- Enter the distance traveled (d) in meters (m) - this is optional but can be used for verification
- Enter the acceleration (a) in meters per second squared (m/s²) - this is optional but can be used for verification
- Click the "Calculate" button to compute the velocity change and other parameters
Principle of Operation
This calculator is based on the basic kinematic equations of motion. The primary formula used is:
v = v₀ + a·t
Where:
- v = final velocity
- v₀ = initial velocity
- a = acceleration
- t = time interval
Applications
This calculator can be used in various physics and engineering applications including:
- Automotive engineering for calculating acceleration and deceleration
- 航空航天 for calculating spacecraft velocity changes
- Sports science for analyzing athlete performance
- Engineering for machinery and equipment movement analysis
Example Calculation
Suppose a car accelerates from 0 m/s to 20 m/s in 5 seconds. What is the acceleration?
Using the formula: a = (v - v₀) / t = (20 m/s - 0 m/s) / 5 s = 4 m/s²
So the car has an acceleration of 4 m/s².
