the weight of an object makes the maintain same state of motion
that is wrong inertia is the correct answer. look it up in the dictionary
Inertia is a property of matter in which an object resists a change in motion.
Newtons laws of physics
friction
inertia
volume is the amount of space a object occupies therefore it is a property
volume is the amount of space a object occupies therefore it is a property
A force
An object in motion tends to stay in motion.
Volume is a property of an object. You can have a cubic millimeter of water or a cubic kilometer of water; the properties of the water itself will be no different.
Motion is calculated by comparing it to something else which may or may not be stationary. Hence you are measuring it's motion relative or in relation to the other object.
Inertia.
Have the force at a constant right angle to the motion. (Centripetal force always acts at right angles to the motion of the object, this is what makes it go around in a circle)
