Why does an object of greater mass experience more friction than an object of lesser mass?

Explanation

### Step-by-Step Solution:

1. **Understanding Friction**: Friction is a force that opposes the motion of an object. It occurs when two surfaces come into contact with each other. The amount of friction depends on the nature of the surfaces and the force pressing them together.

2. **Role of Mass**: The mass of an object affects the weight of that object. Weight is the force exerted by gravity on the mass of the object and is calculated using the formula:
\[ \text{Weight} = \text{mass} \times \text{gravity} (W = mg) \]
