B Time
C Speed
D Kinetic energy
E Acceleration

Answer 1

Answer:

speed

kinetic energy

acceleration

Answer 2

Acceleration-  magnitude and direction

Explanation:

• Vector is that the quantity which has magnitude that acts during a particular direction is described.
• Acceleration may be a vector quantity that's it has both magnitude and direction. When an object features a positive acceleration then the acceleration occurs within the same direction because the movement of the thing.
• A vector has magnitude and direction and it doesn't have position, long as its length isn't changed that's a vector is not altered if it's displaced parallel to itself.
• It is commonly represented by an arrow whose direction is that the same as that of the number, whose length is proportional to the quantity’s magnitude.
