Answer 12

Vector Quantity

Question 13

(side note) A quantity that has magnitude and direction and that is commonly represented by a directed line segment whose length represents the magnitude and whose orientation in space represents the direction.

Answer 13

Vector

Question 14

Refers to the total force acting on an object.

Answer 14

Net Force

Question 15

Without a force applied to an object, what would they do.

Answer 15

Remain still.

Remain in motion (if already in motion).

Question 16
