What kind of energy is used when roller skating?
Kinetic Energy. Kinetic is moving energy and potential energy is how far it could potentially move yet is staying still.
How does potential energy and kinetic energy change during a roller caster ride?
Assuming no energy is lost to air resistance or friction, then the potential energy at the highest point is equal to the kinetic energy at the lowest point of the ride.
Where is the greatest amount of potential and kinetic energy in a roller coaster?
The greatest amount of potential energy of a roller coaster is at its highest point. Remember, potential energy is relative: an apple hanging from a tree has far more potential energy relative to the ground than the same apple sitting on a table on the top floor of a sky scraper relative to the table. Now, the roller coaster itself has no kinetic energy (its not moving), but the "cart" or "coaster" does. The greatest point of kinetic energy of the coaster is the point where it is moving the fastest. The more speed the more kinetic energy. The more height above a specific point the more potential energy.
What form of energy does everything have?
There are several types of energy. potential energy is something that has the potential to move, like a roller coster at the top of the slope. Kinetic energy is the energy of something in motion, like the roller coster while it is hurtling down. Everything has potential energy.
How much do roller blades weigh?

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
What kind of energy is used when roller skating?
Kinetic Energy. Kinetic is moving energy and potential energy is how far it could potentially move yet is staying still.
A 45.0 kg skater is skating down a hill on roller blades at a speed of 10.0 m's What is the kinetic energy of the skater?
Kinetic Energy = (1/2)(m)(v2) where m=mass of object, v=velocity of object Substituting values into the equation. Kinetic Energy = (1/2)(45)(10)2 = 2250 J
What is the kinetic energy of a 45.0 kg skater who is skating down a hill on roller blades at a speed of 10.0 m per s?
kinetic_energy = ½mv² = ½ × 45 kg × (10 m/s)² = 2250 Joules.
Where in the the motion of a roller coaster does it have the kinetic energy?
The back of a roller coaster has the most kinetic energy.
When does a roller coaster increase kinetic energy?
The roller coaster increases kinetic energy when its velocity is increasing.
Where is the kinetic energy the highest on a roller coaster?
The cars of a roller coaster reach their maximum kinetic energy when at the bottom of their path.
Can you use roller blades for figure skating?
If you are crazy enough to try, I don't see why not :)
In energy transformations when a roller coaster is at the top of the hill the kinetic energy is?
Kinetic energy comes from movement. If the roller coaster is moving at the top of the hill, it has kinetic energy. if the rollercoaster isn't moving then it has potential energy.
What is an example kinetic energy?
a roller coster
Does the roller coaster need kinetic energy to move down the tracks?
If its moving it has kinetic energy
When does a roller coaster reach its maximum kinetic energy?
maximum kinetic energy when at the bottom of their path.
