The word "Rotate" spins into mind.
When a planet spins on its axis it is said to rotate. (Think of a top.)
If the displacement-time graph is parallel to the time axis, the object is at rest. This is because the displacement is not changing over time, indicating that the object is not moving.
I believe no scientist said exactly this. It is the (two) electrons in the same orbital that must have opposite spins. And the scientist who said that was Wolfgang Pauli in 1925. (Pauli exclusion principle)
Thomas Edison.
It won't be located on any of the axis. It would be said to be on x-axis or on y-axis (or) it would be said to be the origin accordingly.
When an object is not in motion, it is said to be at rest.
Uranus is sometimes referred to as the "sideways planet" because it spins on an axis that is tilted almost 98 degrees
The vertical axis is a reference axis usually denoted as y-axis in Cartesian co-ordinate system. It can be said that a vertical axis is the axis perpendicular to a reference horizontal surface.
Such an object is said to be in free fall.
The object is said to be in free fall, such as in orbit.
When the net torque acting on an object is zero, the object is said to be in rotational equilibrium. This means that the object will not rotate around its axis and will remain in a stable position.
The object is said to be in free fall.
