Due to ______ball rolls less far on a ground covered with grass or stones as compared to on a smooth ground

Options

A. Force of friction
B. Static friction
C. Net force
D. Dynamic friction

Answer

**Step-by-Step Solution:**

1. **Understanding the Motion of the Ball**: When a ball is rolled, it moves forward due to the initial force applied to it. However, this motion is influenced by various forces acting on it.

2. **Identifying the Force of Friction**: The primary force that opposes the motion of the ball is the force of friction. Friction acts at the contact surface between the ball and the ground.

3. **Comparing Different Surfaces**: The amount of friction depends on the nature of the surface. A smooth surface has less friction compared to a rough surface like grass or stones.

4. **Effect of Surface Irregularities**: On a rough surface, such as grass or stones, there are more irregularities. These irregularities create more contact points between the ball and the surface, leading to increased friction.

5. **Conclusion on Distance Rolled**: Due to the higher friction on rough surfaces, the ball experiences greater resistance, which causes it to roll a shorter distance compared to when it rolls on a smooth surface.

6. **Final Statement**: Therefore, due to increased friction on the ground covered with grass or stones, the ball rolls less far compared to a smooth ground.
