Final Velocity Formula:
From: | To: |
The final velocity calculation determines the speed of an object after undergoing acceleration over a certain distance, using the equation of motion that relates initial velocity, acceleration, and displacement.
The calculator uses the final velocity formula:
Where:
Explanation: The formula calculates final velocity by considering the object's initial velocity, the acceleration produced by the applied force (a = F/m), and the distance over which this acceleration occurs.
Details: Calculating final velocity is essential in physics and engineering for analyzing motion, predicting outcomes of collisions, designing safety systems, and understanding the effects of forces on objects.
Tips: Enter initial velocity in m/s, force in newtons, mass in kilograms, and displacement in meters. Mass must be greater than zero, and displacement must be non-negative.
Q1: What if the initial velocity is zero?
A: If initial velocity is zero, the formula simplifies to \( v = \sqrt{2 \left( \frac{F}{m} \right) s} \), which represents the velocity gained from rest under constant acceleration.
Q2: Can this formula be used for deceleration?
A: Yes, if the force is acting opposite to the direction of motion (negative force value), it will result in deceleration and reduced final velocity.
Q3: What are the units for each parameter?
A: Velocity in m/s, force in newtons (N), mass in kilograms (kg), and displacement in meters (m).
Q4: Does this formula assume constant acceleration?
A: Yes, this equation assumes constant acceleration (a = F/m) throughout the displacement.
Q5: What if the mass is very small or zero?
A: Mass cannot be zero (division by zero error). For very small masses, the acceleration becomes very large, resulting in high final velocities.
