In the context of types of forces and free-body diagrams, which quantity is defined as a measure of the force of gravity on an object?

• A. Mass
• B. Weight
• C. Tension
• D. Normal force

Answer: (B)

Verified step by step guidance

1. Understand that the problem is asking for the quantity that measures the force of gravity acting on an object.
2. Recall that mass is a measure of the amount of matter in an object and does not depend on gravity.
3. Recognize that weight is the force exerted on an object due to gravity, which depends on both the mass of the object and the acceleration due to gravity.
4. Remember the formula that relates weight (W) to mass (m) and gravitational acceleration (g): \(W = m \times g\).
5. Identify that tension and normal force are other types of forces but do not represent the force of gravity on an object.
