Q. If the net force acting on an object is in the positive x-direction, the object moves only in the positive x-direction.
It is not true, the object will accelerate only in the x-direction, but it may be traveling in the y-direction and it could continue to do so making the path it follows a parabola. Think about a ball kicked off a cliff. There is a net force only in the y-direction (gravity) so the ball will accelerate downwards while continuing with a constant horizontal velocity.

What is Vapor Density? Vapour density is the density of a vapour in relation to that of hydrogen. It may be defined as mass of a certain volume of a substance divided by mass of
Electric Potential: Electric Potential verifies the flow of charge. Its unit is volt, represented as "v".
It is the energy possessed by a body because of the interactive forces inside the object. This may be defined as the work done in assembling all the particles of a body in a exact
