What is the difference between object moves wint uniform acceleration and object moves with no acceleration?
An object moving with uniform acceleration has a uniform change in velocity over time, and its velocity-time graph will be a straight line with either a positive or negative slope. An object moving with no acceleration has constant velocity, and its velocity-time graph will be a straight, horizontal line with zero slope. Refer to the related link for illustrations.
What is the example where acceleration is either uniform or non uniform?
If the graph of speed versus time is a straight line, then the acceleration is constant/uniform. If the graph is curved or has a sharp corner, the acceleration is non-uniform, i.e. not constant. A uniform acceleration means the speed changes by fixed amount every unit of time, e.g. +3 m/s every second.
Can acceleration ever be negative?
Acceleration is negative when the object is moving in the opposite direction. on a graph the line would be in the negative quadrant.
What is the nature of velocity time graph of a body moving with uniform retardation?
A body moving at a uniform speed may have a uniform velocity, or its velocity could be changing. How could that be? Let's look. The difference between speed and velocity is that velocity is speed.
Which of the following describes a displacement vs time graph that looks like this?
Constant velocityZero acceleration and/or Moving object
What is the difference between object moves wint uniform acceleration and object moves with no acceleration?

What is the importance of uniform acceleration graph in physics what is instantaneous velocity?
The slope of a velocity-time graph that shows uniform acceleration is the actual acceleration. Instantaneous velocity is the velocity of a body at a particular moment in time.
What is the example where acceleration is either uniform or non uniform?
If the graph of speed versus time is a straight line, then the acceleration is constant/uniform. If the graph is curved or has a sharp corner, the acceleration is non-uniform, i.e. not constant. A uniform acceleration means the speed changes by fixed amount every unit of time, e.g. +3 m/s every second.
What is the area under the un uniform acceleration time graph?
Velocity.
What part of the graph represents uniform positive and negative acceleration Calculate this acceleration.?
The answer depends on whether the graph is that of speed v time or distance v time.
What kinematic concept distance velocity acceleration etc of the moving object does the slope of the graph represent?
acceleration
Can acceleration ever be negative?
Acceleration is negative when the object is moving in the opposite direction. on a graph the line would be in the negative quadrant.
How will you interpret this graph in terms of the speed and acceleration of the moving car?
My interpretation is that the car and any motion, like the graph, do not exist.
Which distance time graph most closley represents an object moving with a uniform motion?
wave
How is an object moving if a slanted straight line on a speed versus time graph represents its motion?
A straight slanted slope on a velocity-time graph indicates that the object is moving with a constant acceleration.
If an object is moving at unifrom acceleration what is its velocity?
A body moving at a uniform speed may have a uniform velocity, or its velocity could be changing. How could that be? Let's look. The difference between speed and velocity is that velocity is speed with a direction vector associated with it. If a car is going from, say, Cheyenne, Wyoming to the Nebraska state line at a steady speed of 70 miles per hour, its velocity is 70 miles per hour east. Simple and easy. Uniform speed equals uniform velocity. (Yes, I-80 isn't perfectly straight there. Let's not split hairs.) But a car moving around a circular track at a uniform speed is constantly changing direction. Its speed is constant, but its velocity is changing every moment because the directionit is going is changing. Speed is uniform, but velocity isn't. As asked, uniform speed is a uniform distance per unit of time. And this will yield a uniform distance per unit of time in its velocity, but the direction vector may be uniform or it may be changing each moment, as illustrated.
