Every 2 and a half minutes you gain 1 energy until it goes up to your maximum energy. You can also get energy by getting certain magical coins, which also increases your maximum energy.
It will take one year for the tree to reach half its maximum height. Since the tree doubles in height each year, it will be at half its maximum height the year before it reaches its full height.
It's kinetic energy is highest when it is about half way to the top. The gravitational potential energy is highest when it is about to fall back down.
no
This is called a half pipe.
i think instead of energy,u meant light.if that's the case,most of it is lost and some is absorbed the suspended particulate matter.
A skateboard that measures 7and half feet across.
The summation of potential and kinetic energy of an object is constant. When the potential energy of an object decreases the kinetic energy increases. Assume a falling stone from some high point above ground. At the beginning, the potential energy is maximum while the kinetic energy is minimum or zero. While the stone is falling, the kinetic energy increases while the potential energy increases (with the summation of both is constant). When the stone reaches the ground, the kinetic energy is maximum and the potential energy is zero.
This is a trick question with the 'twice half' words. The energy is 1050 J which is PE at the apex, it is travelling vertically, there is no air resistance, and that energy has been totally converted to KE when the projectile hits the ground.
Get a book for building skateboard ramps, and follow the directions.
Half pipes, and empty pools, a couple of rails around too
