Velocity Equation:
From: | To: |
The velocity equation (v = u + a×t) is a fundamental formula in physics 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 kinematics.
The calculator uses the velocity equation:
Where:
Explanation: This equation assumes constant acceleration and calculates how an object's velocity changes over time under that acceleration.
Details: Calculating velocity is essential in physics, engineering, and many real-world applications including vehicle motion analysis, projectile tracking, and understanding basic motion principles in mechanics.
Tips: Enter initial velocity in m/s, acceleration in m/s², and time in seconds. Time must be a non-negative value. The calculator will compute the final velocity in m/s.
Q1: What if acceleration is negative?
A: Negative acceleration (deceleration) will result in a decrease in velocity over time, which may result in a negative final velocity if the deceleration is sufficient.
Q2: Does this equation work for variable acceleration?
A: No, this equation assumes constant acceleration. For variable acceleration, integration methods are required.
Q3: What are typical units for these measurements?
A: While we use m/s for velocity and m/s² for acceleration in this calculator, other units can be used as long as they're consistent.
Q4: Can this calculate initial velocity if other values are known?
A: Yes, the equation can be rearranged to solve for any variable if the other three are known.
Q5: What is the difference between velocity and speed?
A: Velocity is a vector quantity (has magnitude and direction), while speed is a scalar quantity (magnitude only). This equation calculates velocity, which can be positive or negative.
