question 7
which one of the following is not a vector quantity?
a. force
b. acceleration
c. weight
d. mass

Explanation:

Step1: Recall vector - scalar definitions

Vectors have magnitude and direction, scalars have only magnitude.

Step2: Analyze each option

Force has magnitude and direction (e.g., a push in a certain direction), acceleration has magnitude and direction (change in velocity per unit time in a direction), weight is a force due to gravity and has direction towards the center of the Earth and magnitude, while mass is a measure of the amount of matter and has only magnitude.

Answer:

d. mass
