Can the motion of a body be accelerated even when it is moving uniformly?

Youre getting a little confused here...
VELOCITY is a measure of speed and distance, and has the unit m/s (meter per second)
ACCELERATION is a measure of a rate of change of velocity, and has the units m/s-squared (meters per second squared)
The body can be anything, think of a pendulum weight on a length of string, if you hold on to an end and start to spin faster and faster. Its acceleration is increasing at a uniform rate. But the direction of the body is constantly changing about a given point (a fixed point about where you hold the string)
So yes the direction of velocity can change

Which type of motion is exhibited by a freely falling body?
Accelerated motion.
Can a body have zero velocity and still be accelerating?
No. A velocity indicates a speed and direction. An acceleration is a change in speed or direction.
How could the uniformly accelerated motion be modified to study the acceleration of a freely-falling body?
At short distances - up to a few kilometers - gravity can be considered constant, and therefore, a body in free fall (i.e., neglecting other forces, such as air resistance) will be uniformly accelerated. Over longer distances, the force of gravity is no longer the same; this will have to be considered for the "modification" (for example, less force = less acceleration). Close to the Earth's surface, in practice, air resistance has to be considered (but this is no longer "free fall").
What is the theory of discussion of non-accelerated rectilinear motion?
A rectilinear motion is a motion along a straight line. It can be one, two, or three dimensional. Non-accelerated motion is when a body is in motion, but there isn't a force to speed it up or slow it down. Therefore, non-accelerated rectilinear motion would be a motion along a straight line that has no force trying to speed it up or slow it down.
Describe uniformly accelerated motion in an inclined plane?
a body sliding down an inclined plane also moves with constant acceleration on account of gravity, but the acceleration down the plane is very much less than the acceleration of free falling body, especially if the angle made by the plane with the horizontal is small
What can you say about the motion of a body if it's velocity-time graph is a straight line inclined with the time-axis?
uniformly accelerated motion
Which type of motion is exhibited by a freely falling body?
Accelerated motion.
What can you say about nature of motion of a body if it's displacement time graph is a curve?
the body is in accelerated motion.
Is the motion of satellite around the earth uniform or accelerated?
Accelerated because when a body changes its direction It will accelerate.
Can a body have zero velocity and still be accelerating?
No. A velocity indicates a speed and direction. An acceleration is a change in speed or direction.

Can a body move with a constant velocity in an accelerated motion?
No. The definition of acceleration is change in velocity.

Were Aristotle's predictions of heavenly motion quantitative or qualiative?
I. Aristotle's Theory of Motion • Two basic principles: I. No motion without a mover in contact with moving body. II. Distinction between: (a) Natural motion: mover is internal to moving body (b) Forced motion: mover is external to moving body
When do we say that a body is in motion?
That means that it is moving.
