Mass is a measure of how much matter an object has. Weight is a measure of how strongly gravity pulls on that matter.
The notation 2N typically means double the amount of a variable or object N. So, 2N is twice the value of N.
Newtons Second Law was F=ma, means the force(F) acting on object is equal to mass(m) of object times it's acceleration(a).
Velocity includes both speed (magnitude of the velocity) and direction, while speed is just the magnitude of the velocity without any indication of direction. So velocity is a vector quantity, whereas speed is a scalar quantity.
The upward force exerted by a liquid or gas on an object immersed in it is called buoyant force. This force is a result of the pressure difference between the top and bottom of the object, and it opposes the weight of the object, causing it to float or rise.
Psychological distance refers to the perceived difference between a person and an object, event, or person, which can impact how that person thinks, feels, or behaves towards it. This concept is often used to explain how individuals may react differently to situations depending on the perceived distance involved.

The difference between roughness and flatness is that one, flatness, is the shape of an object. Roughness is the surface or texture of an object.
