A body in uniform motion has no net force acting on it. That means that either
there are no forces at all, or else that all the forces acting on it add up to zero.

Why a body in uniform circular motion experiences a force?
A body can execute circular motion only if there's a force acting on it, directedtowards the center of the circle. Without that force, circular motion isn't possible.If you expected us to get into "centrifugal" force, forget about it. No such force exists.
What is the difference between increasing velocity and uniform velocity?
Increasing velocity means that the body is accelerating and a force is acting on the body to produce the acceleration. Uniform velocity means that there is no acceleration or deceleration and so no force acts on the body. (Note that in practice we cannot achieve perpetual motion because of either the decelerating force of gravity or friction).
Circular motion occurs only near the earths surface?
False. A contra example; Triton has a circular motion about Neptune Newton's first law of motion: a body remains a rest or in uniform motion in a straight line unless acted upon by a force. If there is a centripetal force towards a point acting on a body that is moving then that body will have circular motion. The body and point do not have to be on earth.
A body falling freely from a hight towards the earth moves with uniform?
It moves with uniform acceleration,because it has a constant force acting on it (its weight).
A body is in equilibrium when it's?
when it is at rest, or in constant uniform motion with net force and moment of zero (no acceleration)

What are the effects of force in motion?
A force acting on a body accelerates it in the direction of the force.
What is the motion of a body when only the force of garvity is acting on the body?
Free Fall
What is the difference between increasing velocity and uniform velocity?
Increasing velocity means that the body is accelerating and a force is acting on the body to produce the acceleration. Uniform velocity means that there is no acceleration or deceleration and so no force acts on the body. (Note that in practice we cannot achieve perpetual motion because of either the decelerating force of gravity or friction).
What type of motion can be produced by balanced forces?
According to Newton's laws of motion, a body at rest remains at rest and a body in motion remains in uniform motion unless it is acted upon by a force. This law is also known as the law of Inertia. If the forces are balanced, then there is no net force acting on the body and so it cannot produce any motion. It can only allow pre-existing motion to continue.
Does the Law of Inertia state that a body remains at rest or continues in a state of uniform motion unless a force act on it?
The Law of Inertia states that a body continues in a state of uniform motion unless a force act on it.
What is the motion of body when only the force of gravity is acting on it?
Free falling.
When a body falls freelyto the ground its motion has uniform motion?
No. "Uniform motion" means motion at a constant speed in a straight line. But the speed of a body falling freely to the ground is continuously increasing, in response to the force of gravity.
Define law of transmissibility of forces?
"The condition of equilibrium or motion of a rigid body is remain unchanged, if a force acting on the rigid body is replaced by another force of the same magnitude and same direction but, acting anywhere along the same line of action."
Circular motion occurs only near the earths surface?
False. A contra example; Triton has a circular motion about Neptune Newton's first law of motion: a body remains a rest or in uniform motion in a straight line unless acted upon by a force. If there is a centripetal force towards a point acting on a body that is moving then that body will have circular motion. The body and point do not have to be on earth.
What causes an object to change speed of the direction of motion?
A force acting on the body, along its line of motion.
The motion of a body when only force of gravity is acting on the body?
zero velocity =)
