Zero acceleration
If the change in velocity is zero, i.e., either the object is at rest or moving with uniform velocity, then the object is said to have zero acceleration. Example: A car parked in the basement of an apartment or a train moving with a constant speed of 90 miles..
Zero work
When the applied force and the displacement make an angle 90 o to each other, the work done is zero. This is because cos 90 = 0. A person carrying a briefcase, moves on a horizontal road. Since, the gravitational force acts vertically downwards and the displacement of the person is in..

Absolute zero of temperature
when T = 0, then C = 0 This leads us to the following definition of 'absolute zero of temperature'. Absolute zero of temperature may be defined as that temperature at which the rms velocities of the gas molecules become zero. In other words, all molecular motion ceas..

I really liked this tutoring. Helped me alot and gave me more ways to work a problem. awesome help and I even got the idea on these problems - kimi
I need tutoring from tutorvista till th end of my schooling. Tutors are not only experts they are brilliant enough to make a student like me understand the concepts of differentiation and functions.
I have experienced very innovative way of learning, I joined online tutoring at Tutorvista few months back when I was in grade 10, I scored really well in grade 10 and ny parents were really happy.
Looking for More Help!
