Answer:
1. C. Speed
2. D. Velocity
3. A. Acceleration
Explanation:
1. Speed is a scalar quantity that refers to "how fast an object is moving." Speed can be thought of as the rate at which an object covers distance.
2. Velocity-a vector quantity which refers to "the rate at which an object changes its position." Velocity is the rate of change in displacement with respect to time. Since displacement is a vector quantity, then velocity is also a vector quantity. It has both magnitude and direction.
3. Acceleration is a vector quantity that is defined as the rate at which an object changes its velocity. An object is accelerating if it is changing its velocity.
