How the skate park simulation can be used to eplain the law of conservation of energy?
In the skate park simulation, as the skater moves along the track, the potential energy at the top of each ramp is converted into kinetic energy as the skater descends. The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another. This principle is demonstrated in the simulation as the skater's total energy (potential + kinetic) remains constant throughout the ride.
Do you want to reduce friction when you are sitting on a park bench?
Normally you would not want to do so. If there was no friction, you would slip right off the bench onto the ground. You need some friction in order to stay in one place.
What are two major types of energy?
SOLAR ENERGY Solar energy, radiant light and heat from the sun, has been harnessed by humans since ancient times using a range of ever-evolving technologies. Solar energy technologies include solar heating, solar photovoltaics, solar thermal electricity and solar architecture, cooking, water treating process, photovoltaics, etc., which can make considerable contributions to solving some of the most urgent problems the world now faces. Solar power is the conversion of sunlight into electricity, either directly using photovoltaics (PV), or indirectly using concentrated solar power (CSP). Concentrated solar power systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam. Photovoltaics convert light into electric current using the photoelectric effect. HYDROELECTRIC ENERGY Most hydroelectric power comes from the potential energy of dammed water driving a water turbine and generator. The power extracted from the water depends on the volume and on the difference in height between the source and the water's outflow. This height difference is called the head. The amount of potential energy in water is proportional to the head. A large pipe (the "penstock") delivers water to the turbine. TIDAL ENERGY A tidal power plant makes use of the daily rise and fall of ocean water due to tides; such sources are highly predictable, and if conditions permit construction of reservoirs, can also be dispatchable to generate power during high demand periods. Less common types of hydro schemes use water's kinetic energy or undammed sources such as undershot waterwheels. WIND ENERGY Wind power is the conversion of wind energy into a useful form of energy, such as using wind turbines to make electricity, windmills for mechanical power, windpumps for water pumping or drainage, or sails to propel ships.In a wind farm, individual turbines are interconnected with a medium voltage (often 34.5 kV), power collection system and communications network. At a substation, this medium-voltage electric current is increased in voltage with a transformer for connection to the high voltage electric power transmission system.The surplus power produced by domestic microgenerators can, in some jurisdictions, be fed into the network and sold to the utility company, producing a retail credit for the microgenerators' owners to offset their energy costs. GEOTHERMAL ENERGY Geothermal electricity is electricity generated from geothermal energy. Technologies in use include dry steam power plants, flash steam power plants and binary cycle power plants. Geothermal electricity generation is currently used in 24 countries, while geothermal heating is in use in 70 countries. Electricity generation requires high temperature resources that can only come from deep underground. The heat must be carried to the surface by fluid circulation, either through magma conduits, hot springs, hydrothermal circulation, oil wells, drilled water wells, or a combination of these. This circulation sometimes exists naturally where the crust is thin: magma conduits bring heat close to the surface, and hot springs bring the heat to the surface. If no hot spring is available, a well must be drilled into a hot aquifer. Away from tectonic plate boundaries the geothermal gradient is 25-30°C per kilometre (km) of depth in most of the world, and wells would have to be several kilometres deep to permit electricity generation.[2] The quantity and quality of recoverable resources improves with drilling depth and proximity to tectonic plate boundaries.
On a cold winter day why would an iron post in a park feel much colder to the touch than a wooden bench?
Metal is a better conductor of heat than wood, meaning it can quickly transfer heat away from your hand, making it feel colder. The iron post would lose heat more rapidly to the surroundings than the wooden bench, which retains heat better.
Why would an iron post in a park feel much colder to touch than a wooden bench?
Iron is a better conductor of heat than wood, so it quickly transfers heat away from your skin, making it feel colder to the touch. Wood, on the other hand, is a poorer conductor of heat, so it doesn't transfer heat away from your skin as efficiently.
What energy does a park bench have?
A park bench primarily possesses potential energy due to its position and structure, as it is static and has the potential to be used by people sitting on it. Additionally, if the bench is made of materials that can absorb heat, it may have thermal energy from sunlight or the surrounding environment. However, it does not have kinetic energy unless it is moved. Overall, its energy is mostly related to potential energy and thermal energy in its environment.

What is the difference between kinetic energy and potential energy?
Kinetic energy is the energy in the movement.Potential energy is stored energy, ready to be used.K.E-motion energyP.E-energy stored during displacement of springs that tend to restore to original position of springKinetic energy is the energy found in every object in motion .Gravitational Potential Energy is the enegry stored in an object because of its height. For example, the energy that water has before it goes over a waterfall. Chemical potential energy is the energy that a substance can release by undergoing a chemical reaction, for example gasoline which releases energy when it is burned. Mechanical potential energy would be the kind stored in a compressed spring. Radioactive materials such as uranium have nuclear potential energy.Kinetic energy is the energy of motion.. while something is moving.. and potential energy is the energy being stored up for the object TO move.A ball rolling has kinetic energy... when you pull back a spoon to throw food at someone, when you pull back and hold it there, it has potential energy (potential to be kinetic, that is)Potential energy is the capacity for doing work that a body possesses because of itsposition or condition. While kinetic energy is energy a body possesses because it is in motion.kinetic energy is moving energy or energy used in preforming an action.potiental energy is sitting energy or energy that is being saved up.potential- when energy is stored.kinetic- when energy is movingPotential energy is stored energy, when building up to it's highest point the energy is released as kinetic energy. For example potential energy is the energy gathered when moving slowly up an amusement park ride, when you reach the top the potential energy reaches it's limit and is realeased as kinetic energy when you rocket downwards.
Mark and Ann took a two week hiking trip through Yosemite National Park While hiking through the park they witnessed two large blocks of rock break away from Glacier Point What is the initial transf?
Potential energy is converted into kinetic energy.

What is the energy transformation taking place when a person jogs at the park?
Chemical energy is transferred into kinetic energy. When a person jogs, motion is produced.
