What does it mean if an object is motionless?
Actually, a motionless object is just a special case of an object that is maintaining constant velocity. Its velocity is constantly 0 m/s. Understand that we are saying if no outside force is applied, the velocity of the object (which is its speed and direction) will remain constant.
Can an object be motionless in space?
Our universe works similarly, but we’re embedded on a three-dimensional space instead of a two-dimensional one. There is no ‘still’ that is not relative to some other object. So yes, you can be still with respect to one object, but you’ll be moving with respect to every other object.
Under what conditions will an object remain motionless?
The Law of Inertia states that matter remains in its state of motion and direction unless acted upon by a force. Motionless objects will stay motionless unless acted upon by some force. Moving objects continue at a constant speed unless acted upon by some force.
What forces act on a motionless object?
The gravitational force can act in the direction of motion (ie. an object falling), friction can exist when an object is stationary (it could be what prevents the object from moving), and objects only experience a normal force when resting on a surface.
Can an object be motionless while forces are acting on it?
Both Galileo and Newton inferred that because of inertia, objects which are not being pushed or pulled, if initially motionless, will remain motionless. His First Law states that an object with a net force of zero acting on it will remain at rest, if initially at rest, or it will maintain a constant velocity.
Is it possible to stand still?
It is almost impossible for the human body to stand still. We make constant, tiny and almost invisible body movements, also called micro movements, according to research from the University of Oslo.
Can you ever be still in space?
Yes, it is possible to be essentially standing still in relationship to the Sun. There are many comments and an answer telling you why you can’t and, as far as they go, they are correct. If you move far enough away from our sun, it become just another star.
Can spaceships stop in space?
Space ships do not stop when they run out of fuel. While outer space does contain gas, dust, light, fields, and microscopic particles, they are in too low of a concentration to have much effect on spaceships. As a result, there is essentially zero friction in space to slow down moving objects.
