Ch-02: Vectors | MCQs

Ch-02: Vectors 
Multiple Choice Questions 

This chapter delves into the representation of vectors in 2-D space, breaking them down into two perpendicular components, which enables the calculation of various vector operations. A key concept explored in this chapter is the product of two vectors, also known as the dot product or scalar product, which results in a scalar value rather than another vector. The dot product of two vectors, A and B, is calculated as the sum of the products of their corresponding components.

The document contains multiple choice questions related to vectors, covering topics such as vector components, resultant forces, scalar and vector products, and angles between vectors. Each question presents a scenario or concept and provides four answer options. The questions are designed to test understanding of vector mathematics and physics principles.


Ch-02: Vector - MCQs | PDF


Vectors are a fundamental concept in physics, used to describe physical quantities with both magnitude and direction. In essence, vectors provide a mathematical representation of quantities like displacement, velocity, acceleration, and force, allowing us to analyze and predict their behavior. A vector's magnitude represents its size or amount, while its direction indicates the way it points or acts. By combining vectors using operations like addition, subtraction, scalar multiplication, and vector multiplication, we can solve complex problems in physics and engineering. Mastering vectors is essential for understanding motion, forces, and interactions, and provides a powerful tool for problem-solving in physics and beyond.

Unit-02: Shooting Stars

Unit-02: Shooting Stars
1 Define meteors?
Ans: Meteors are small pieces of comets that exploded long ago and travel through space. They follow large, looping paths similar to the original comet’s orbit. When they enter Earth’s atmosphere, friction makes them white-hot. This causes them to appear as bright streaks of light in the sky.
