uniform acceleration
uniform velocity
uniform speed
Answers
Answer:
1.The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time. Velocity is equivalent to a specification of an object's speed and direction of motion
2.Speed can be thought of as the rate at which an object covers distance.
3. the actual path covered by a body
4. a displacement is a vector whose length is the shortest distance from the initial to the final position
5. Acceleration is the rate of change of velocity in a certain time.
6. Uniform or constant acceleration is a type of motion in which the velocity of an object changes by an equal amount in every equal time period
7. The condition in which a body covers equal distance in an equal interval of the time is known to be uniform velocity
8. If an object covers equal distance in equal interval of time, then time speed graph of an object is a straight line parallel to time axis then body is moving with a uniform speed.

hope this helps u
pls mark me the brainliest
Velocity - Velocity is the rate at which the position changes.
Speed - Speed is the distance traveled per unit of time. It is how fast an object is moving.
Distance - Distance is the total movement of an object without any regard to direction.
Displacement - Displacement is defined to be the change in position of an object.
Acceleration - Acceleration is a vector quantity that is defined as the rate at which an object changes its velocity.
Uniform Acceleration
Zero acceleration refers to the uniform velocity. An object can have zero acceleration and still be under motion.
Uniform Velocity
When a body covers equal distances in equal intervals of time (however small may be the time interval) in a specified direction, the body is laid to be moving with uniform velocity.
Uniform Speed
A body is said to be in uniform motion if its velocity does not change with time. For a body in uniform motion, net external force is always equal to zero.
