What else can I help you with?
Is it true that all physical quantity which has a direction and a magnitude is a vector?
I think so, yes; that's basically what the concept of a "vector" in physics is all about. (There are also more abstract vectors in math and physics, but something that has a magnitude and a direction would be enough to quality as a vector.)
Where do you find vector?
Vectors are used whenever there is a measurement in which not only the magnitude is relevant, but also the direction. Typical uses of vectors include position, velocity, acceleration, force, torque, and others.
Can the resultant of three vectors be zero also define is it possible for two vectors?
Yes. Any number of vectors, two or more, can result in zero, if their magnitudes and directions are just right. One vector can result in zero only if its magnitude is zero.
What is the angle between the two vectors if their sum has a magnitude of 2F?
We can't answer that without also knowing the magnitude of the individual vectors.
Can three vectors not in one plane give zero resultant?
No. For three vectors they must all lie in the same plane. Consider 2 vectors first. For them to resolve to zero, they must be in opposite direction and equal magnitude. So they will lie along the same line. For 3 vectors: take two of them. Any two vectors will lie in the same plane, and their resultant vector will also lie in that plane. Find the resultant of the first two vectors, and the third vector must be along the same line (equal magnitude, opposite direction), in order to result to zero. Since the third vector is along the same line as the resultant vector of the first two, then it must be in the same plane as the resultant of the first two. Therefore it lies in the same plane as the first two.
Is resultant a vector quantity?
The resultant of two vectors cannot be a scalar quantity.
What are the different methods in adding vectors?
Vectors can be added using the component method, where you add the corresponding components of the vectors to get the resultant vector. You can also add vectors using the graphical method, where you draw the vectors as arrows and then add them tip-to-tail to find the resultant vector. Additionally, vectors can be added using the trigonometric method, where you use trigonometry to find the magnitude and direction of the resultant vector.
Is it true that all physical quantity which has a direction and a magnitude is a vector?
I think so, yes; that's basically what the concept of a "vector" in physics is all about. (There are also more abstract vectors in math and physics, but something that has a magnitude and a direction would be enough to quality as a vector.)
Is any quantity having a positive and negative values a vector?
No, not necessarily. A vector is a quantity that has both magnitude and direction. While it can have positive and negative values, not all quantities with positive and negative values represent vectors. Vectors must also obey the rules of vector addition and scalar multiplication.
Where do you find vector?
Vectors are used whenever there is a measurement in which not only the magnitude is relevant, but also the direction. Typical uses of vectors include position, velocity, acceleration, force, torque, and others.
What does a vector consist of?
A vector consists of a magnitude (length) and a direction in space. It is typically represented by an arrow showing magnitude and direction, and may also have components along different axes. Vectors are used in physics and mathematics to represent quantities like force, velocity, and displacement.
How are scalar and vector quantities similar?
Scalar and vector quantities are both used in physics to describe properties of objects. They both have magnitude, which represents the size or amount of the quantity. However, the key difference is that vector quantities also have direction associated with them, while scalar quantities do not.
How do you represent vectors graphically?
Vectors can be represented graphically using arrows. The length of the arrow represents the magnitude of the vector, and the direction of the arrow represents the direction in which the vector is pointing. Vectors can also be represented by coordinates in a coordinate system.
How can you use the pythagorean theorem to add two vectors that are perpindicular to each other?
Construct the rectangle that contains the right angle subtended by the vectors. Calculate or construct the diagonal of the rectangle. The diagonal is the hypotenuse of a right triangle with the two vectors as sides. The hypotenuse is also the vector that is the sum of the two original vectors. Calculate the magnitude of that vector by applying the theorem.
Can the resultant of three vectors be zero also define is it possible for two vectors?
Yes. Any number of vectors, two or more, can result in zero, if their magnitudes and directions are just right. One vector can result in zero only if its magnitude is zero.
What does vectors an in science?
In science, vectors are quantities that have both magnitude and direction. They are used to represent various physical phenomena, such as force, velocity, and acceleration. For example, a vector can indicate not only how fast an object is moving (magnitude) but also the direction in which it is moving. This makes vectors essential for understanding and analyzing motion and interactions in physics and engineering.
The differences between scalar quantities and vector quantities?
A scalar quantity is just a number e.g. 3 miles A vector quantity is a number with directions e.g. 3 miles south So the difference between them is that vector has a particular direction to go with but a scalar quantity is just a number.
