What does decreased in MAGNITUDE mean?
I think magnitude means how much of something or how long the sides are or the angle.
smaller, size of scalar or magnitude of vector
if a vector is defined by
V = x + i y
then its magnitude |V| is sqrt(x^2 + y^2)
if you are going 5 mph east
and 5 mph north
then the magnitude of your velocity is the speed = sqrt(5^2+5^2) = 5 sqrt 2
When we say that something has "decreased in magnitude," it means that the quantity or value of that something has become smaller. In terms of magnitude, we usually refer to the size, extent, or intensity of a physical quantity.
To understand the concept of a decrease in magnitude, let's consider an example. Suppose we have a positive number, let's say 10. If this number decreases in magnitude, it will become smaller in value. For instance, if it decreases by 5 units, the new value will be 5.
The concept of magnitude can also be applied to physics, such as the magnitude of a force or the magnitude of an earthquake. In these cases, a decrease in magnitude would mean that the force or seismic activity has become weaker, smaller, or less intense.
In summary, when we talk about a decrease in magnitude, we mean that the size, extent, or intensity of something has become smaller.
