hastighedsændring
Hastighedsændring, often translated as acceleration, is a fundamental concept in physics describing 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 hastighedsændring can occur in three ways: an increase in speed, a decrease in speed (often called deceleration), or a change in direction.
Mathematically, average hastighedsændring is defined as the change in velocity divided by the time interval over
The SI unit for hastighedsændring is meters per second squared (m/s²). For example, if an object's velocity
Hastighedsændring is directly related to force through Newton's second law of motion, which states that the
