5. A force is described by its _____________ and ____________.
A mass; direction***
B strength; mass
C strength; direction
D mass; acceleration
The answer is A
The correct answer is C) strength; direction.
To understand why, let's break down the options:
A) Incorrect - A force is not described by its mass. Mass is a property of an object and is not directly related to its force.
B) Incorrect - Strength is not the correct term to describe a force. Strength refers to the intensity or amount of force exerted but does not fully characterize the force itself.
D) Incorrect - While mass and acceleration can be related to a force through Newton's second law (F = ma), they do not fully describe a force.
C) Correct - A force is described by its strength (also known as magnitude or intensity) and its direction. The strength of a force tells us how powerful or intense the force is, while the direction indicates the line or path along which the force acts. Together, these two components fully characterize a force.
To answer this question, one could use their knowledge of the properties of forces or search relevant sources, such as textbooks or reliable websites, to find the correct answer.
