Final velocity (v) can be calculated by adding the initial velocity (u) to the product of acceleration (a) and time (t). The formula for final velocity is v = u + at.
Final velocity is the velocity of an object at the end of its motion, while initial velocity is the velocity of an object at the beginning of its motion. In other words, final velocity is the result of adding the initial velocity and the change in velocity due to acceleration.
If there is no acceleration, the final velocity will be equal to the initial velocity. In this case, the formula for final velocity will be v = u, where u is the initial velocity.
Yes, final velocity can be negative. A negative final velocity indicates that the object is moving in the opposite direction of its initial velocity.
Final velocity is typically measured in meters per second (m/s) or kilometers per hour (km/h). The units will depend on the units used for initial velocity, acceleration, and time in the calculation.
