Nopeusmuutosta
Nopeusmuutos, often translated as acceleration, is a fundamental concept in physics that describes the rate at which an object's velocity changes. Velocity itself is a vector quantity, meaning it has both magnitude (speed) and direction. Therefore, a change in either speed or direction, or both, constitutes acceleration. In simpler terms, acceleration is how quickly something speeds up, slows down, or changes its path.
The standard unit for acceleration in the International System of Units (SI) is meters per second squared
Acceleration can be positive, meaning the velocity is increasing in the direction of motion, or negative, often
