**How to calculate initial potential energy?!? Yahoo Answers**

22/09/2009Â Â· How to calculate initial potential energy? A 30kg mass slides over a distance of 6.0m from the top of a rough plane inclined at 30 degrees to the horizontal. 282J of work is done against friction as the mass reaches the bottom of the plane.... Note that the initial kinetic energy of the weight is zero because it has zero velocity. Let's now calculate the velocity by applying the relationship between net work and the change in kinetic energy.

A 36.0 child runs with a speed of 2.50 tangential to the rim of a stationary merry-go-round . The merry-go-round has a moment of inertia of 556 and a radius of 2.31....The initial kinetic energy of the puck is almost entirely converted to thermal energy and sound in this inelastic collision. Strategy Momentum is conserved because â€¦

**how to find initial kinetic energy-Oyxter Znaleziska**

In this article, we will look at how to calculate kinetic energy. I.e., the work done is equal to the final kinetic energy â€“ the initial kinetic energy, or the net work done on the object is equal to the change in the objectâ€™s kinetic energy. But, what if the force was not constant? For this case, we need to use calculus. We use the calculus definition for work done, with as our net how to get gamertags from unactive accounts 22/09/2009Â Â· How to calculate initial potential energy?

## How To Find The Initial Kinetic Energy

### That must equal the change in kinetic energy. That is precisely the physical content in @exploringplanet's equations. The point is that the mass doesn't matter. Whatever the mass, both the (change in) potential energy and (change in) kinetic energy are propotional to it. So you can effectively "cancel" the mass dependence and calculate what happens to the velocity.

- Note that the initial kinetic energy of the weight is zero because it has zero velocity. Let's now calculate the velocity by applying the relationship between net work and the change in kinetic energy.
- Calculate by dividing the loss by the original kinetic energy. The average kinetic energy before the collision is 1.35 J and the average kinetic energy immediately after the collision is 0.272 J, so the loss of kinetic energy is 1.08 J.
- That must equal the change in kinetic energy. That is precisely the physical content in @exploringplanet's equations. The point is that the mass doesn't matter. Whatever the mass, both the (change in) potential energy and (change in) kinetic energy are propotional to it. So you can effectively "cancel" the mass dependence and calculate what happens to the velocity.
- Yes, the work increases the energy of the block, and since it is at the same height (on the floor) and no energy was lost to friction, the KE of the block is 8 N * 320 N = 2560 J. But then 2560 J = 1/2 * 250 kg * v 2
