### Physics problems for class 9 – numericals with solutions

Physics problems for class 9 (CBSE)–numericals set1 This set of Physics problems for class 9 students of CBSE/ICSE/HS boards cover Newton’s Laws of motion, Force, linear motion equations and Gravitation. Hope the students will like this set and try to solve the numerical problems themselves. I am providing the solutions as well, but you should

### Physics problems – Solutions of selected numericals(set 1)

Physics Problem set with Solution Some of the posts in this blog include sample physics problem sets along with the post content. Readers can always try those. We have decided to publish the solutions of selected problems from different sets/posts, as we have done in this post. Physics Problem Q set source: If you want

### Escape velocity – Definition, Derivation of equation and Values

Escape velocity  From the term Escape Velocity itself we get an idea of its definition. It’s a velocity that helps to escape – isn’t it? But Escape from what and how? Should we use the term velocity or we should use the term speed? This is what we are going to discuss today in our

### Orbital Velocity of Satellite-derivation of 3 expressions

Orbital Velocity of Satellite Definition of Orbital velocity: Orbital Velocity of a satellite is the minimum velocity it has to maintain to continue its circular motion in its orbit. We know for a circular motion to continue, a force called centripetal force is required to work upon the object in circular motion. And this force
