which example best describes a restoring force
the force applied to move a spring back to its original length
the force applied to compress a spring and shorten its length
the force applied to stretch a spring and increase its length
any force that is applied to a spring to change its length
A restoring force can be best described as the force applied to move a spring back to its original length.
The example that best describes a restoring force is the force applied to move a spring back to its original length. When a spring is stretched or compressed from its equilibrium position, it exerts a force in the opposite direction to return to its original length. This force is known as the restoring force. So, the correct option is the force applied to move a spring back to its original length.
The example that best describes a restoring force is the force applied to move a spring back to its original length.
To understand why, let's first define what a restoring force is. A restoring force is a force that tends to bring an object back to its equilibrium position, or its original state. In the context of a spring, the equilibrium position is the spring's natural length, where it is neither compressed nor stretched.
Now, when a spring is compressed or stretched away from its equilibrium position, a restoring force is exerted on it. This force acts in the opposite direction of the displacement, aiming to return the spring to its original length.
So, in the given options, the example of the force applied to move a spring back to its original length best describes a restoring force. When the spring is compressed or stretched, this force acts in the opposite direction to bring it back to its original, equilibrium state.
Here's a step-by-step explanation of how to identify the example that represents a restoring force:
1. Identify the definition of a restoring force as the force that brings an object back to its equilibrium position.
2. Understand that a compressed or stretched spring experiences a force aiming to return it to its original length.
3. Analyze each option to see which corresponds to a force that moves the spring back to its original length.
4. By the process of elimination, you will conclude that the force applied to move a spring back to its original length is the example that best describes a restoring force.
