I'm A J Anagha. I'm doing my third year of Bachelors' in Phyiscs at Assumption College, Autonomous, Changanacherry, India. Throughout my college life, I have always kept myself as an active student by partaking in various co-curricular activities, representing my college at the National Students Parliament. I'm also a member of the college students union and various other clubs and organisations like the United Nations Academic Impact, National Service Scheme etc.
To talk a bit about my working experience, I'm currently working part time as a subject matter academic expert at Chegg India Pvt Ltd. Also, I tutor physics to students in my locality for the past 2 years. I've worked a Software Test Engineer Intern at Tata Consultancy Services during December, 2019 - January, 2020.
To talk a bit about my international experiences, I was among the ten students from India who get selected for the Japan-Asia Sakura Science Exchange Student. Recently, I got selected for the T P Nedungadi Internship Award, which is a two month fully funded internship abroad and was awarded to two students from Kerala, India.

In Physics, a force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. In this video, the concept of force and torque is demonstrated with the practical application of changing the flat tire of the car.
