Muscle tissue has cells that shorten to exert force. This shortening of muscle cells is what allows for movement and physical activity.

Muscle tissue shortens to exert force. Muscle cells contain special proteins that slide past one another to produce a contraction, which results in the overall shortening of the muscle tissue and generates force.
The force you exert on a sponge when you squeeze it is called compression force.
The force you exert towards yourself is called self-force or self-interaction force.
The force that you exert on a lever can be called the effort force. The lever has three parts. They are: the fulcrum, the load, and the effort force. This can also be classified as the input force. The force that you exert to perform a task is known as the input force.
No, you exert less force when you are closer to the fulcrum. The farther you are from the fulcrum, the more leverage you have and the less force is needed to move an object.
