The instantaneous velocity will increase with time. If the motion is accelerated, no matter if the acceleration is constant, or variable, the instantaneous velocity will increase. Variation of acceleration describes how to change in velocity is changing.

What happen to the instantaneous velocity in a non-uniformly accelerat...
Explanation:
Instantaneous velocity in non-uniformly accelerated motion:
- In non-uniformly accelerated motion, the acceleration of an object changes over time.
- Instantaneous velocity is the velocity of an object at a particular instant in time.
- As the acceleration changes in non-uniformly accelerated motion, the velocity of the object also changes.
Effect on instantaneous velocity:
- It increases: In non-uniformly accelerated motion, the instantaneous velocity of the object increases when the acceleration is positive. This means that the object is speeding up.
- It decreases: On the other hand, when the acceleration is negative, the instantaneous velocity of the object decreases. This indicates that the object is slowing down.
- It varies as the acceleration: The instantaneous velocity changes in accordance with the changes in acceleration. If the acceleration is constant, the velocity may either increase or decrease at a constant rate. However, in non-uniformly accelerated motion, the velocity changes at a varying rate depending on the changing acceleration.
- It remains constant: The instantaneous velocity does not remain constant in non-uniformly accelerated motion. It is a dynamic quantity that changes with changes in acceleration.
Therefore, in non-uniformly accelerated motion, the instantaneous velocity of an object changes in accordance with the changing acceleration, either increasing or decreasing as the acceleration changes.
