Multiple Choice
In the context of types of forces and free-body diagrams, which of the following is NOT a force?
A
Normal force
B
Frictional force
C
Tension force
D
Mass
Verified step by step guidance1
Step 1: Understand the concept of a force in physics. A force is an interaction that causes an object to accelerate, change its velocity, or deform. Forces are vector quantities, meaning they have both magnitude and direction.
Step 2: Review the given options: Normal force, Frictional force, Tension force, and Mass. The first three are well-known types of forces that act on objects in various situations.
Step 3: Define each force briefly: Normal force is the support force exerted by a surface perpendicular to the object; Frictional force opposes the relative motion between two surfaces in contact; Tension force is the pulling force transmitted through a string, rope, or cable.
Step 4: Recognize that Mass is not a force. Mass is a scalar quantity representing the amount of matter in an object. It does not cause acceleration by itself but relates to inertia and weight (which is a force).
Step 5: Conclude that among the options, Mass is NOT a force, while the others are types of forces commonly represented in free-body diagrams.
