______________ does not reveal about the direction of the motion. To describe how fast an object moves and the direction of its motion, we need the vector concept of _____________.
- A Speed - Velocity
- B Distance - Time
- C Acceleration - Velocity
- D Mass - Force
That's Correct!
It's Wrong!
Speed is a scalar quantity that only describes how fast an object is moving, without regard to its direction. Velocity, on the other hand, is a vector quantity that includes both the speed and direction of motion. To fully describe the motion of an object, we need to know both how fast it is moving and in what direction it is moving.
