Inertia makes it stay still and determines how hard it would be to get it moving
Mass
Static friction is the frictional force needed to overcome the initial resistance of an object at rest and set it in motion. This force is required to counteract the initial inertia of the object and is called static friction because it acts when an object is stationary.
Inertia is the tendency of an object to resist a change in its motion. Objects with more mass have more inertia. The more mass an object has the harder it is to change its motion. Thats is how inertia effects and object. (Don't worry I got this from my Science Textbook)
Static weight is the weight of an object when it is not in motion, while dynamic weight takes into account the additional forces acting on an object when it is in motion, such as inertia and acceleration. Dynamic weight can be greater than static weight due to these additional forces.
To counteract the effects of inertia, you can apply a force in the opposite direction of motion. By doing so, you can overcome the resistance caused by inertia and change the object's velocity. Implementing techniques such as pushing, pulling, or braking can help counteract inertia effectively.
While analyzing the mechanism if mass of the body and inertia force if it is not considered then it is called static force
The mass of the object and the velocity of the object.
"inertia"
The mass of an object determines its inertia. Inertia is the resistance of an object to changes in its motion, and objects with greater mass have greater inertia.
Static inertia is when a body at rest wants to stay at rest, or a body that is moving at a constant speed stays at the constant speed.
By adding or losing eletrons (friction)
the mass of an object. The greater the mass of an object, the greater its inertia. Additionally, inertia also depends on the velocity of the object - the faster an object is moving, the greater its inertia.
