✿ Define :
✠ Uniform Circular Motion ↴
Uniform Circular motion is a movement of an object along the circumference of a circle or rotation along a circular path. It can be uniform, with constant angular rate of rotation and constant speed, or non-uniform with a changing rate of rotation.
✠ Inertia ↴
Inertia is the resistance of any physical object to any change in its velocity. This includes changes to the object's speed, or direction of motion. An aspect of this property is the tendency of objects to keep moving in a straight line at a constant speed, when no forces act upon them.
✠ Balanced Forces ↴
Balanced forces are those that are opposite in direction and equal in size. Balanced forces are considered to be in a state of equilibrium. When forces are balanced there is no change in direction. Combined forces that are balanced are always equal to zero.
✠ Unbalanced Forces ↴
When two forces acting on an object are not equal in size, we say that they are unbalanced forces. The overall force acting on the object is called the resultant force . If the forces are balanced, the resultant force is zero. A moving object changes speed and/or direction in the direction of the resultant force.

Answer:
(a). uniform circular motion is a is a motion of an object traveling at a constant ( uniform) speed on a circular path.
(b). inertia is the inability of a body to change its state of rest or of uniform motion along a straight line by itself
(c). if the total force or the resultant force on a body is zero, the applied force are called balanced force such forces can neither move a body at rest nor stop a body in motion
(d). a condition when opposite forces acting on an object are not equal . the net force acting on the object is not zero..
