When is the motion of an object said to be accelerating?
The motion of an object is said to be accelerating when its velocity is changing. This change in velocity can be an increase or decrease in speed or a change in direction. Acceleration is a vector quantity, meaning it has both magnitude and direction.
What is the difference between saying that one quantity is proportional to another and saying it is equal to another?
When one quantity is proportional to another, it indicates that one quantity is dependent on the other by a factor and increases/decreases with the other quantity. When the two quantities are equal, the output of both the quantities is said to be the same.
Diference between velocity and speed?
Velocity has speed and direction. Speed only has speed. --------------------------------------------------------------------------------------- Speed is a scalar quantity having only magnitude But velocity is a vector quantity having both magnitude and direction. So a body is said to move with uniform speed around a circle but not with uniform velocity as the direction is always changing.
What is the difference between the accuracy and the validity of a measurement?
Accuracy is a characteristic of the exactness or correctness of an answer. Validity is a characteristic of the answer's appropriateness to the question. For example, if I said, "It is approximately 47 billion, 312 million, 697 inches from New York to Chicago" that may be a very accurate answer to the question "How far is it from New York to Chicago", but it's not very valid - most people don't measure distance between cities in inches.
What does weight mean?
It could be said that it is how much force is gravity putting on the object, weight is related to mass and gravity, such that : weight = mass x gravity It is a common mistake thinking that weight is same as mass, mass is the amount of quantity in an object, and doesn't vary according to position as weight does. It means that you put fat on
What is mks system?
when the unit of any physical quantity is measured in terms of meter or kilogram or second or in combination of these then it is said that unit is in MKS system.
What does units agree mean?
In mathematics, two quantities are said to be in units agreement if they have the same units of measure. For example, if two quantities are both measured in meters, then they are in units agreement. If one quantity is measured in meters and the other is measured in centimeters, then they are not in units agreement.
If a quantity increases as a second quantity increases and decreases as the second quantity decreases the two quantities are said to be?

What might cause the quantity demanded of a particular good to double if price remains constant?
Just a guess, but it could be that the price of said good is an undercut of other providers, then the masses will buy said good will have demand up-ing(I'm no economics guy, I'm just a kid, so dont say crap if I'm wrong

When the percent change in price is equal to the percent change in quantity demanded then demand is said to be?
When the percentage change in price is equal to the percentage change in quantity demanded then demand is said to be unit elastic. There are 3 kinds of price elasticity of demand.
A numerical result is said to have good precision if?
agrees closely with other measurements of the same quantity. Precision is how close together several readings of the same thing are.
