FAQs on Fun Video: What are Vectors? Video Lecture - Mathematics (Maths) Class 12 - JEE

1. What are vectors in mathematics?
Vectors in mathematics are mathematical quantities that have both magnitude and direction. They are commonly represented as arrows in a coordinate system, where the length of the arrow represents the magnitude of the vector and the direction of the arrow represents the direction of the vector.
2. How are vectors different from scalars?
Vectors differ from scalars in that scalars only have magnitude, while vectors have both magnitude and direction. Scalars can be represented by a single number, such as temperature or mass, whereas vectors require both magnitude and direction to be fully described.
3. Can vectors be added or subtracted?
Yes, vectors can be added or subtracted using vector addition or subtraction. When adding or subtracting vectors, their magnitudes are combined according to the rules of vector addition or subtraction, respectively, and their directions are taken into account.
4. What are some real-life examples of vectors?
There are several real-life examples of vectors. Some common examples include velocity (which has both magnitude and direction), force (applied in a specific direction), displacement (change in position with direction), and acceleration (change in velocity with direction).
5. How are vectors used in physics?
Vectors play a crucial role in physics as they are used to describe various physical quantities. They are used to represent forces, velocities, accelerations, and many other quantities that have both magnitude and direction. Vectors allow for a more comprehensive understanding and analysis of physical phenomena.
