In physics, the terms "velocity" and "speed" have specific meanings:
- Speed refers to the magnitude of the velocity vector and is a scalar quantity. It represents how fast an object is moving without any regard to its direction.
- Velocity, on the other hand, is a vector quantity that includes both the speed and the direction of motion. It describes the rate at which an object changes its position in a specific direction.
So, to be precise, it would be more accurate to say "to increase speed" rather than "to increase velocity" when discussing the acceleration of an object. Acceleration refers to the rate of change of velocity or speed, depending on the context.
