Friction
There is no such thing as a "stationary" object. Every motion is always measured relative to something else, which, coincidentally, is what the question is all about. The thing against which motion is measured is called the "reference frame".
A force that resists or works against motion is called friction. Friction occurs when two surfaces rub against each other, causing a resistance that opposes the motion of an object.
The force is called friction. Friction occurs when two objects rub against each other, causing resistance to motion.
Frictional force is sometimes called a "perverse force" because it works opposite to the direction of an object's motion, creating resistance and making it harder for the object to move. This frictional force can be seen as going against the desired motion of the object, hence the term "perverse."
It is called self-propulsion when something moves by itself, typically using its own energy or mechanism to generate motion.

Newton's First Law is called his First Law of Motion. It states that an object in motion tends to stay in motion unless influenced by something else that slows or stops its motion. Likewise, an object at rest - not moving - tends to stay at rest unless influenced by something else that starts it moving.
Friction is the force that makes it hard to pull something. Friction occurs when two surfaces rub against each other, creating resistance to motion. This resistance increases as the surfaces press harder against each other.
Because friction is exerted against the direction of motion
