Solution

ForceForce can be defined as an effort that changes the state of motion or shape of an object. It can be a pull or push.The quantity of force is expressed by the vector product of mass $\left(m\right)$ and acceleration $\left(a\right)$. The equation or the formula for force can mathematically be expressed in the form of: $F=ma$The standard international system of unit (SI unit) is expressed in newton $\left(N\right)$.When force is applied to a fixed body, it will deform its shape and size.Muscular ForceIn order to charge the shape of the dough, the force needs to be exerted with our hands.When we exert force with our hands, we use the muscles present in our hands.Hence, this force is termed as a muscular force.Hence, the force exerted to change the shape of the dough is muscular force.
