Answer:
Direction
Step-by-step explanation:
The question is testing on vector and scalar quantities.
What are vector quantities and scalar quantities?
- Quantities with both magnitude and direction are known as vector quantities while those with only magnitude are known as scalar quantities.
What are the examples of vector and scalar Quantities?
- Vector quantities examples- Velocity, force, displacement, etc
- Scalar quantities examples - Speed, distance, temperature, mass, etc
What would be the difference of speed and velocity then?
- Speed and velocity differ in that velocity has both magnitude and direction (vector quantity) while speed has magnitude only (scalar quantity).
Further Explanation;
- Velocity refers to the rate of change in displacement of a body in motion
- It is given by, Velocity = Displacement ÷ time
- Speed on the other hand is the rate of change in distance of body.
- It is calculated by, Speed = Distance ÷ time
- Displacement is the distance in a specified direction.
- Velocity and displacement are vector quantity in that they have both magnitude and direction.
- Speed and distance on the other hand lack direction and thus are scalar quantity since they only have magnitude.
