A Shovel and Dirt Interaction

This interaction between a shovel pushing on dirt and the dirt pushing back is known as the resistance force.

Understanding Resistance Force

When you try to shovel dirt, the dirt exerts a force that opposes your shoveling motion. This force is what we refer to as the resistance force. It is a reaction force that occurs when an object tries to move through a resisting medium.

Resistance force can be experienced in various everyday activities, such as pushing a heavy object on the ground, trying to stir a thick liquid, or even gardening. In the case of shoveling dirt, the resistance force from the dirt makes it challenging for you to move the shovel smoothly through it.

It is important to understand the concept of resistance force as it helps us comprehend the dynamics of interactions between objects and their environment. By recognizing and accounting for resistance forces, we can better predict the behavior of objects in different circumstances.
