Acceleration Formula:
| From: | To: |
The acceleration formula v = u + at is a fundamental equation in kinematics that calculates the final velocity of an object given its initial velocity, constant acceleration, and time elapsed. This equation is derived from the basic principles of motion.
The calculator uses the acceleration formula:
Where:
Explanation: The formula calculates how an object's velocity changes over time when subjected to constant acceleration. Positive acceleration increases velocity, while negative acceleration (deceleration) decreases it.
Details: Calculating final velocity is essential in physics, engineering, and various real-world applications such as vehicle safety analysis, projectile motion studies, and mechanical system design.
Tips: Enter initial velocity in m/s, acceleration in m/s², and time in seconds. Time must be non-negative. All values can be positive or negative depending on direction.
Q1: What does negative acceleration mean?
A: Negative acceleration indicates deceleration or acceleration in the opposite direction to the initial velocity.
Q2: Can this formula be used for variable acceleration?
A: No, this formula only applies when acceleration is constant. For variable acceleration, calculus-based methods are required.
Q3: What are typical units for this equation?
A: Standard SI units are meters per second (m/s) for velocity, meters per second squared (m/s²) for acceleration, and seconds (s) for time.
Q4: How does initial velocity affect the result?
A: Initial velocity serves as the starting point. The acceleration then modifies this velocity over the given time period.
Q5: What if time is zero?
A: If time is zero, the final velocity equals the initial velocity regardless of acceleration, as no time has passed for acceleration to act.
