The sum total of all the forces acting on the object is zero.
Rocks sit still and stay objects.
The gravity of all the planets and the alignment of them.
it is a force called gravity.
Objects move or stay still based on the balance of forces acting upon them. If the net force is nonzero, the object will accelerate in the direction of the force. If all forces are balanced (net force is zero), the object will remain still or continue at a constant velocity.
Objects at rest stay at rest because of inertia, which is the tendency of an object to resist changes in its motion. Inertia causes the object to maintain its state of rest unless acted upon by an external force.
its a solid because gases spread out< liguads move slightly and solids stay still
what causes the motion of objects
Inertia is the tendency of an object to resist changes in its state of motion. Objects with more mass have greater inertia, so they are harder to accelerate or decelerate. Inertia also causes objects in motion to stay in motion and objects at rest to stay at rest unless acted upon by an external force.
The objects in the solar system stay in orbit due to the gravitational pull between them and the sun, which keeps them in place as they constantly move around it. This gravitational force acts as a centripetal force, balancing the objects' tendency to move in a straight line and keeping them in stable orbits.
Gravity is the force that causes objects to have weight. Gravity is the attraction between two objects with mass, such as the Earth and an object on its surface, that causes objects to be pulled towards each other. The strength of gravity depends on the masses of the objects and the distance between them.
The gravitation
Gravity is the force which keeps them there.
