An example of the periodic motion is Earth's revolution. In this, the motion repeats itself after regular intervals of time. In oscillatory motion, the object moves back and forth about a mean position like a vibrating spring or pendulum. It is a type of periodic motion. Although, oscillatory motions are periodic, however, not vice versa. Oscillatory motion typically follows sinusoidal patterns and involves a restoring force.

No, IIT Delhi offers admission to its BTech course based on JEE Main and JEE Advanced scores only. Candidates selected based on exam scores are required to participate in the JoSAA counselling. This is the final criteria for admission. However, to be eligible for the BTech courses, students should have passed Class 12 with a minimum of 75% aggregate with Science subjects (i.e., Physics, Chemistry and Mathematics). 

Students should use our NCERT Applications of Derivatives Solutions to begin their JEE preparation as a resource to build strong foundation.  Our solutions follow the lates CBSE Class 12 syllabus which make them a complete resource for CBSE Boards prepaation, Yet for competitive exam like JEE, Student must go beyond NCERT and refer to advanced-level books like arihant, cengage or coaching material availble to them.

Yes, your chances of getting into SASTRA University are good, particularly for Stream 1 (70% of seats) where your JEE Main score and 12th percentage are considered. Your 79.57 JEE Main percentile and 98.1% in 12th are competitive scores for SASTRA. 

Conservative forces (like gravity or spring force) conserve mechanical energy and do not depend on the path taken. The work done by the conservative forces is recoverable.
Non-conservative forces (like friction or air resistance) dissipate energy as heat or sound. It depends on the path. When non-conservative forces act, mechanical energy is not conserved.

Energy is measured in joules (J). It is the capacity to do work while power is the rate of using energy or doing work. Power is measured in watts (W). One watt equals one joule per second. Power talks about how fast the work is done, and energy is about how much work is possible. 

Candidates scoring good ranks must go for JEE Advanced exam. If not, then they must should focus on improving their JEE Main score to get into CCSU by taking multiple mock tests and practicing previous year's question papers. Candidates can identify their areas of proficiency and topics where they need improvement. If they can achieve full marks in their practice sessions, they can start preparing for JEE Advanced. However, if they cannot score full marks, it is recommended that they appear for multiple mock test series for more practice. 

When without slipping a body rotates and translates simultaneously is called rolling motion, such as a wheel on a road. It is the combination of rotatory and translatory motion. The point of contact has zero velocity relative to the surface in pure rolling. It is a condition in which there is no slipping or sliding during rolling.
