Can a vectors magnitude be negative
WebVectors a and b are always right angles to each other, so you can use the Pythagorean theorem to determine the magnitude (or length) of a+b. It is true that the angles between a and a+b or b and a+b can be any angle between (but not including) 0 and 90 degrees, but that doesn't matter when calculating the Pythagorean theorem. Web2. Which of the following is a vector: a person’s height, the altitude on Mt. Everest, the velocity of a fly, the age of Earth, the boiling point of water, the cost of a book, Earth’s population, or the acceleration of gravity? 3. Give a specific example of a vector, stating its magnitude, units, and direction. 4.

WebIt is convenient to draw vectors starting at the origin, but it is NOT necessary. 5 is just the vector's LENGTH, and -3 is just the vector's HEIGHT. You can draw the vector starting at any point on the graph, but you have to make sure it has a length of 5 and a height of negative 3. For example: If you drew the vector starting at point (1, 1 ... WebTwo vectors are equal if they have the same magnitude and the same direction. Just like scalars which can have positive or negative values, vectors can also be positive or negative. A negative vector is a vector which points in the direction opposite to the reference positive direction .
