Is it possible that a body be in accelarated motion under a force acting on a body yet no work is being done by the force?

Yes, that is possible. For example, an object in circular motion, accelerated towards the center. The force (and the acceleration) is normal (perpendicular) to the movement; thus, the dot product between the force and the displacement is zero.

Can an object be in motion if no external forces are acting on it?
yes. external forces ALTER an object's motion... but once it starts moving and has no external forces being applied on it, it will go in a straight line with constant velocity (Newton's 1st Law of Motion)
True or false if you know an objects mass and acceleration you can determine the net force being exerted on the object?
False. You will know nothing at all about any force acting perpendicular to the direction of motion.
If an object has a natural tendency to move with constant velocity why do you need to keep pushing a cabinet to move it with constant velocity?
If the cabinet is on a floor, it is being acted upon by earth's gravity and friction with the floor. Newton's law says an object in motion will continue in motion unless acted upon by another force. Consider the outside forces acting on the cabinet. They are acting on the cabinet to slow it down, and you need to keep pushing it to overcome them and keep the cabinet moving.
Why is motion possible?
That question would really be tough to answer, because perpetual motion is not possible.
Why is an object going in a circular motion constantly accelerating?
This is not strictly true; an object in orbit, going in a circular motion, at least from a human perspective, is not accelerating. However, any object going in a circular motion that is not orbiting another object is being contained in a circle artificially, either by a tether or by thrust, that would go in a straight line if no other force were acting on it, is experiencing "acceleration," which is not necessarily "going faster" as might be assumed.
How do you start acting quick as possible?
Being able to act in a movie is not a 'do it now' thing. You have to hire an agent who will find a place in acting for you.

What is the cost per mile for thorium fusion engine?
The cost will depend on the mass being moved and other forces acting on it when in motion such as drag and friction.
What is the easiest way to get into acting school?
Being good at acting.

How has th economy today improved racially since the Emancipation Proclamation of 1863?
African-Americans were able to get better jobs, and the economy underwent an accelarated change from being commodity agriculture-based to manufacturing.
What is the Difference between comedic acting and dramatic acting?
Comedic acting is being funny like a Comedian. Dramactic acting is like Opera

False. You will know nothing at all about any force acting perpendicular to the direction of motion.
What converts rotary motion into linear motion?
There are so many things that use linear motion. Some of them include paper printer, bucket in a well, electric windows in a vehicle and so much more.
What is a different word for being?
acting, human
What motion is the vertical press?
That is an up and down motion being the strongest force the one used in the upward motion.
