In Class 8 Science, when we study the chapter 'Force and Pressure', forces are categorized into Contact and Non-Contact forces. The most common type of contact force we use every day is Muscular Force.
Definition: Force resulting from the action of muscles.
Type: It is a Contact Force.
Users: Applied by humans and all living animals.
Muscular Force is the force exerted by the action of muscles in our body. Whenever we use our body partsālike our hands or legsāto push, pull, lift, or stretch an object, the force applied is generated by our muscles.
Muscular force is strictly a Contact Force. This means that to apply this force, our body must be in direct physical contact with the object (or connected via a stick or a rope). You cannot apply muscular force on an object from a distance without touching it (unlike magnetic force).
We rely on muscular force for almost every physical activity:
Muscular force is the force applied by the action of muscles in the body. It is a contact force. Examples include lifting a bucket of water, walking, kicking a ball, or a bullock pulling a cart.
