Speed is the measure of how fast something is moving. It’s a scalar quantity, meaning it only has magnitude (how much) and not direction. It describes how quickly distance is covered over time, like meters per second or kilometers per hour. Velocity, on the other hand, would include direction, so it’s not just about how fast. Friction is a force that resists motion, and mass is the amount of matter in an object, neither of which describe how fast the object is moving.
