when two bodies change their positions with time, it's termed as motion and if the motion continues it may begin to have velocity,acceleration etc
motion occurs when an object changes its position relative to a reference point.
True. Motion occurs when an object changes its position relative to a reference point. A change in speed indicates a change in the rate of motion, which can result in the object moving at a different pace or direction.
ans: do you mean motion? motion is the meaning to move relative to something else, and it occurs (or is seen to be occurring) when two objects pass each other that have different velocities (not necessarily changing velocities). Without this, you would not be able to perceive motion at all. Motion doesn't mean speed has to change, as that relates simply to acceleration.
Motion occurs when an object changes its position relative to a reference point. This change in position can be caused by a force acting on the object, such as a push or pull. The study of motion is part of the branch of physics called mechanics.
Static friction occurs when two objects are in contact with each other but not moving relative to each other. It acts to prevent the objects from sliding past each other when a force is applied.
That question would really be tough to answer, because perpetual motion is not possible.
The force opposing relative motion of two objects in contact is called friction. Friction occurs when the surfaces of the two objects are in contact and resists the motion between them. It is caused by intermolecular interactions between the surfaces.
Static friction is the type of friction that occurs when objects are not moving relative to each other. It prevents the objects from sliding away from each other when a force is applied.
MOTION: A body is said to be in motion if it changes it's position with respect to it's surrounding. REST: A body is said to be in rest if it does not changes it's position with respect to it's surrounding.
Static friction occurs between two objects that are not moving relative to each other and prevents the objects from sliding against each other.
