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.

Gravitational acceleration is defined as the acceleration of an object caused by the force of gravitation, where all small bodies accelerate in a gravitational field at the same rate relative to the center of mass. Uniform linear acceleration is when a body moves in a straight line and accelerates at a constant rate, and the body is said to have a uniformly accelerated linear motion.
Momentum=mass*velocity
Instantaneous velocity is the rate at which an object is moving in a uniform direction, distance per unit time, at any given instant in time. instantaneous acceleration is the rate at which an object's velocity is changing at any given instant in time
Velocity is the rate of change of distance with time, acceleration is the rate of change of velocity with time.
Speed - is something moving at a constant rate. Acceleration is an increase of the rate an object is moving.

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.
Momentum=mass*velocity
From a kinematic perspective, whenever an object's velocity changes at a constant rate it is in uniform acceleration.From a dynamic perspective, whenever the net force on an object is constant the object will undergo uniform acceleration.
Instantaneous velocity is the rate at which an object is moving in a uniform direction, distance per unit time, at any given instant in time. instantaneous acceleration is the rate at which an object's velocity is changing at any given instant in time
force =mass x acceleration therefore mass = force /acceleration and acceleration = force/mass
It means the object has NO ACCELERATION.
Velocity is the rate of change of distance with time, acceleration is the rate of change of velocity with time.
Speed - is something moving at a constant rate. Acceleration is an increase of the rate an object is moving.
"Uniform acceleration" means that acceleration doesn't change over time - usually for a fairly short time that you are considering. This is the case, for example, when an object drops under Earth's gravity - and air resistance is insignificant. "Non-uniform acceleration", of course, means that acceleration does change over time.
For velocity to be truly uniform, the object must be moving in a straight line. If that is the case then the acceleration is Zero.
1. You will have a uniform acceleration of about 9.8 meters/second2 when an object is in free fall near the Earth's surface - for example, when you drop an object, and air resistance can be ignored. 2. Any situation where the force is constant. 3. Uniform acceleration is often assumed for simplicity, for example, when accelerating a car.
