Can a bullet have more momentum than a truck?
A tiny bullet can have more momentum than a huge truck. A moving car has momentum. If it moves twice as fast, its momentum is TWICE as much.
Does direction matter for momentum?
Momentum is not only dependent on the mass and speed of the target. In a given direction, velocity is distance, so an object’s momentum therefore depends on the direction of motion. This means that an object’s velocity will shift whether the object accelerates or slows down.
What happens when two vectors are equal?
Equal vectors are vectors that have the same magnitude and the same direction. Equal vectors may start at different positions. Note that when the vectors are equal, the directed line segments are parallel. If two vectors are equal then their vector columns are equal.
What do 2 vertical lines mean in geometry?
The symbol for absolute value is two vertical lines. Since opposites are the same distance from the origin, they have the same absolute value. The absolute value of zero is zero.
Can you have a double absolute value?
What if there are two absolute-value expressions? Yes, but only if there are exactly just the two absolute values, so that we can “isolate” each of them, one on either side of the equation.
What does a double absolute value mean?
Most commonly it means the Euclidean norm of the vector a. You could say “the geometric length of a” or “the magnitude of a” to refer to the same concept.
What does 4 dots mean in math?
In logical argument and mathematical proof, the therefore sign, ∴, is generally used before a logical consequence, such as the conclusion of a syllogism. While it is not generally used in formal writing, it is used in mathematics and shorthand.
Does a dot mean multiply?
The dot signifies multiplication. To multiply numeric values, as in “2 multiplied by 3′, enter ‘2*3’, where the symbol ‘*’ can be entered through ‘Shift+8’.
What do the 3 dots tattoo mean?

What do tattooed dots on fingers mean?
Finger Dot Tattoo A single dot often represents a ‘full stop’ – the end of one phase and the start of another. A row of three dots is another popular version of this tattoo. Once often worn by gang members, today, it is associated with living life on your terms.
Why finger tattoos are a bad idea?
Finger tattoos get more chance of an infection. A lot of people tend to forget that a tattoo is an open wound, because it doesn’t really look like one. And open wounds – whether they be a cut, scrape or fresh ink – are much more susceptible to infections than unbroken skin.
