What is the difference between a scalar and a vector ? What are the three components you need then drawing a vector? True or False: Scalar notation can only be positive values. True or False: The value 13.003 has 3 significant figures. True or False: You next homework assignment is due Tuesday May 27, 2014. If vector A={10i+12j}N and B={-5j} N, what is the is the resultant force vector F (in Cartesian vector form)? What is force magnitude, and direction(s). Draw the resultant force ?Explanation / Answer
a) The main difference between a vector quantity and a scalar quantity is that a vector quantity has both magnitude and direction while a scalar quantity has only magnitude and no direction. Some additional scalar quantities are; energy, mass, and density. These also depict a magnitude but cannot define a specific direction.
The difference between vector quantity and scalar quantity is that the magnitude in the vector must be able to move in a given direction. If it cannot move in that given direction, science disqualifies it from being a vector quantity. In the same breath, a scalar quantity only has the magnitude with which it qualifies to be a scalar quantity. As soon as it starts moving in a given direction, the parameters change and it no longer is a scalar quantity.
b) Three things are magnitude, direction and the orientation of the vector
c) FALSE, Scalar notation can have both positive and negative values
d) FALSE, The given statement is incorrect since 13.003 has more than three significant figures
e) The net force will be {10i + 12j } - {5j} = {10i + 7j }
Magnitude = ((10)^2 + (7)^2)^(1/2) = 12.206 units
Direction will be taninv(7/10) = 34.9920202 degrees
