Question

what is meant by postive, negative and zero displacement?
​

Answer 1

Answer:

When an object is speeding up, the acceleration is in the same direction as the velocity. Thus, this object has a positive acceleration.

Explanation:

According to our principle, when an object is slowing down, the acceleration is in the opposite direction as the velocity. Thus, this object has a negative acceleration. In

Zero acceleration is an acceleration, just with zero magnitude. Motion with constant velocity is just a special case of motion with uniform (i.e. zero) acceleration.

• A positive displacement pump displaces the liquid from the suction side to the discharge side by mechanical variation of volume of chamber in the suction side to the discharge side.

• Displacement is represented as a vector in physics. That means we need to provide direction as well as magnitude to define it. The negative sign just represents the opposite direction of the displacement according to your co-ordinate system.

• the object instead of moving through a distance can have zero displacement. Example: If an object travels from point A and reaches to the same point A, then its displacement is zero.
