Velocity is defined by physicists as both speed and direction, that is to say, if you are moving at 30 feet per second in a northerly direction, that is a velocity. Acceleration means a change in velocity. Physicists consider speeding up, slowing down, or changing direction all to be forms of acceleration; in more everyday usage, acceleration us used to mean speeding up and deceleration means slowing down. So, if your speed increases from 30 feet per second to 40 feet per second, that is acceleration.

Velocity is displacement divided by time.
Acceleration is velocity divided by time.
However both graphs are related! If you graph the AREA under the slope of the acceleration graph vs. time, this will be a velocity graph. If you graph the SLOPE of the velocity graph vs. time, this will be an acceleration graph.
When you learn calculus (unless you already know it) you will learn how you can switch between the two.

What is difference between an object moving with uniform acceleration and an object moving with a constant velocity?
A motion with a constant speed will always be moving the same speed A motion with a constant acceleration will constantly be gaining speed, and does not remain moving at the same speed.
What is the acceleration?
Acceleration is the rate at which an object changes its velocity. It can be calculated by dividing the change in velocity by the time taken for that change to occur. Acceleration can be in the same direction as the velocity (speeding up) or in the opposite direction (slowing down).
What interpretation can you derive regarding the motion from the graph of instantaneous speed vs time graph?
The slope of the instantaneous speed vs. time graph gives the acceleration of the object. A horizontal line indicates constant speed, a positive slope indicates acceleration, and a negative slope indicates deceleration. Changes in the slope indicate changes in acceleration.
Why is acceleration a factor in force and not velocity?
Acceleration is a factor in force because force is defined as the rate of change of momentum, which involves mass and acceleration. Velocity is the rate of change of position, and on its own does not impact force in the same way acceleration does. Acceleration directly affects the change in an object's velocity, which in turn influences the force required to produce that change.
How can a position time graph show if an object has constant acceleration?
A position-time graph with a straight line indicates constant acceleration. The slope of the line represents the acceleration, which is constant if the slope remains the same throughout the graph. A steeper slope indicates a greater acceleration, while a shallower slope indicates a smaller acceleration.
