Thanks BenTheMan.
Square root of [sqrt(288) - sqrt(280)] What is the positive square root of [sqrt(288) - sqrt(280)]? I know that the result is 2^1/4[sqrt(7) -...
Now suppose I try to stop a moving ball. When I stop the ball, the ball loses its kinetic energy and I spend some of my energy. And it appears the...
Lets suppose I have a fan attached to a motor in complete vacuum. The electrical energy supplied to the motor is converted into the kinetic energy of...
Prove that the numbers 49, 4489, 444889, 44448889,..... obtained by inserting 48 into the middle of the preceding mumbers are squares of integers....
Can you explain why the direction of angular momentum is perpendicular to both the linear momentum and the distance to the reference point? I mean...
How can angular momentum be conceptually thought of? I find it easy to visualize linear momentum as how difficult it is to stop a body possessing...
There's something I don't understand though. Please go to the thread on Work against gravity if you could help me.
I read in a book under the definition of power. I’ll give it in the same words. “Work done does not depend on time. For example, If a person A lifts...
Thanks I got it now.
Work = Force x Displacement. Right? Let’s consider a frictionless space. Here I apply 100N force to a body and it moves with a constant velocity to...
Can you give me the energy expression for an electron? And also, does the energy of an electron decrease, or does the energy of the Energy shell...
Separate names with a comma.
