What is a 900 in skate boarding?
It's when the skater goes in the air and rotates 900o which is 2 and a half rotations. Normally done is a halfpipe.
How much potential energy does 60 kg skater have at 12 meters above ground?
The skater has potential energy of 7,056 joules.
A 45.0 kg skater is skating at a speed of 12.0 ms The skater coasts to a speed of 6.00 ms How much kinetic energy has the skater lost?
2430
How can energy be conserved as a skater rolls down a ramp?
When rolling down, potential energy is converted into kinetic energy. If there is no friction, this means the skater moves faster and faster. If there is energy (the usual situation), part of this movement energy (kinetic energy) will be converted into heat.
What is the relationship between a potential energy and the height of a skater on a track?
The higher something is, the more potential energy it has stored.
What type of energy is used during speed skating?
There is a large conversion of chemical energy to mechanical energy in the body of the skater. Lots of that! (That may be part of the reason for being out there!) That is what the muscles are doing all the time - converting chemical energy to mechanical energy. The body is a chemical engine, and we convert chemical energy into mechanical energy every moment we are alive. There is more, so let's look! There will be conversion of potential energy to mechanical energy at all time the skater is in motion, too. And mechanical energy is converted to potential energy as well. This may not be obvious, but walking is a constant process of converting potential energy to mechanical energy and vice versa. When we walk, we lean forward and gravity begins to pull us down. We're converting potential energy into kinetic (mechanical) energy. We then put out a foot and lift ourselves back up that tiny bit that we "fell" and that's converting mechanical energy into potential energy because we "lifted" ourselves upright again. Then we start all over with the next step. Make sense? Walking, running or skating all put the same principles into motion. The mechanical energy of friction and its conversion into heat happens in the skates, particularly in the bearings and wheels. The motion - any at all - will create a bit of heat due to friction. The more the motion, the more mechanical energy is converted into heat. Even with good bearings that are properly lubricated, they assembly will warm up. The wheels will be warm to the touch after only a brief time of skating, too. You know why? Yup. Conversion of the mechanical energy of friction into heat energy. There's a lot going on when we skate!
What is the mass of a skater if the potential energy is 600j velocity is 5ms height is 6?
20kg
A 45 kg skater is skating down a hill on roller blades at a speed of 10.0 ms What is the kinetic energy of the skater?
KE=(0.5)(m)(v)^2 KE=225J

Why does the mechanical (total) energy of the skater not change over time?
It certainly does; mechanical energy will be wasted due to friction. Otherwise, if you disregard friction, the fact that the total mechanical energy is conserved follows from conservation of energy.
Is a skater a punk?
No a skater not a punk.
What you need to be a figure skater?
to be an figure skater you have to have determination and confidence.
