Accuracy is how close you're measurement comes to an accepted or given value. I n many cases you do not know what the accepted value is, so you have nothing to compare your measurement with. The more often a measurement is taken with close precision, or reproducibility, the more likely you are to being close to your unknown accepted value.
There is a great short tutorial video covering accuracy and precision at Sciocity dot com
Answer:
<em>529.2N </em>
Explanation:
Given parameters:
Mass of the object = 54kg
Unknown:
Gravitational force acting on the mass = ?
Solution:
To solve this problem, the gravitational force acting on this body is tantamount to the weight of the object.
So;
Weight = mg
m is the mass
g is the acceleration due to gravity
Now;
Weight = 54 x 9.8 = <em>529.2N </em>
The gravitational force acting on the object is <em>529.2N </em>
As per the question the body possesses kinetic energy but the net displacement of the particle is zero.
Before going to explain the type of motion first we have to know the basics of displacement.
The displacement is a vector quantity which has magnitude as well as direction .it is the minimum distance between two points out of all possible paths
Let us consider an example .let a body travels from point A to the point B and again comes to the back to the same point A .here the distance traveled is 2AB but the net displacement is zero.we have to apply this concept to solve this problem.
As the body possesses kinetic energy but the net displacement is zero .
This is in case of an circular motion.in circular motion the body possesses rotational kinetic energy but in every circular rotation ,the net displacement is zero.
One can take an example of oscillatory motion also.here the particle possesses vibrational kinetic energy ,but in each vibration ,the net displacement is zero.
here the answer to your question hope it helps you
