Expression for kinetic energy of a moving body
Consider a body of mass 'm' which is initially at rest. When a force 'F' is applied on the body, let it start moving with a velocity 'V' and cover a distance 's'. The force produces acceleration 'a' in the body. The force 'F' does work when it moves the body ..

We know that all moving objects possess momentum. Momentum of the body is defined as the product of its mass and the velocity. Now let us see how kinetic energy of a body is related to its momentum. Consider a body of mass 'm' moving with a veloc..

To cause a displacement of a body controlled by elastic forces, work has to be done. For example, work has to be done in stretching a spring against the elastic forces. This work will be stored in the body as potential energy. When the deforming force is released..
Internal Energy
Internal energy is one of the most important concepts in thermodynamics. Energy changes in a body sliding with friction. Warming a body increases its internal energy and cooling the body decreases its internal energy. However, wh..

Tutor is an excellent. I would say this tutor is an asset of Tutor Vista.. Excellent Job!!!!!!!
I was very pleased with my sessions the tutors were a great help and helped me through the problems step by step - Molly
I uploaded a worksheet and I wanted to follow it with the tutor so I could learn the technical parts. It took just a few minutes to get the understanding of what I needed with the tutor. I even get through all the examples on the sheet in 25 minutes that we were focused on it.
Hi, I am Ethan, I am in Grade 11. I subscibe to TutorVista tutoring few weeks back and I am liking it.
Looking for More Help!
