momentum
Further answer
Momentum is the reason something keeps moving, it's not really what it's called. Motion or perpetual motion is more like the answer to the question.
The friction of a non-moving object is called static friction. It is the force that prevents the object from moving when a force is applied to it.
The path taken by a moving object is called its trajectory. It describes the route or journey followed by the object as it moves.
The energy of a moving object is called kinetic energy. It depends on the mass and velocity of the object.
The force that keeps an object moving is called inertia. Inertia is an object's resistance to changes in its motion and is related to its mass.
The total path length covered by a moving object is called displacement.

An object moving in a curved path affected only by gravity is called a projectile.
Inertia
The static friction of a non-moving object is called static friction. This type of friction prevents the object from starting to move when a force is applied.
That tendency is called inertia. It is an object's resistance to changes in its motion and is dependent on its mass.
