What two energy transformations happen when you rub two sticks together and fire is started?
When you rub the sticks together, you convert kinetic energy (from moving the sticks) to internal energy, or heat energy - the sticks will warm up. When the heat energy is sufficient to overcome the activation energy of the combustion (activation energy = minimum amount of energy required to start a chemical reaction), the chemical energy in the sticks/whatever you are combusting is converted to heat and light energy
What else can I help you with?
Why did futurism happen?
It started in 1909/1910 - the early 20th century, and is still going on today.
What will happen to plants if there is no heat energy?
the plants will die because heat gives energy to all plants and that is how plants make there own food
What will happen to the atoms or molecules of a substance when it condenses?
When a substance condenses, it turns from a vapor (gas) into a liquid. When this occurs, the atoms/molecules lose some kinetic energy, and don't move as fast. They also become packed closer together, and take up less volume.
What happens when electrons moves to higher energy level?
The electron gains energy.
What would happen if all the protists on earth died?
There would not be enough food food energy for sea creatures to survive.
What energy transformations happen when a person lifts a chair?
Chemical energy from the person's muscles is turned into potential energy.
What types of energy transformations happen to a car that is being drived?
chemical energyenergy conservationfossil fuelsnuclear energyrenewable energy
What energy transformations happen as you eat a hamburger then ride your bike?
When you eat a hamburger, your body converts the chemical energy in the food into mechanical energy to fuel your movements. When you ride your bike, your muscles convert that stored chemical energy into mechanical energy to propel the bike forward. Overall, the energy transformations involve chemical energy from the food being converted to mechanical energy for movement.
What energy transformations happen with a pendulum?
A pendulum undergoes potential energy to kinetic energy conversion as it swings back and forth. At the highest point, the pendulum has maximum potential energy, while at the lowest point, it has maximum kinetic energy. Energy is conserved in this oscillation process.
What are the three energy transformations that take place when you use a flashlight?
The energy transformations that I would mention are as follows:Chemical Potential Energy --> Electrical Energy (In Battery)Electrical Energy --> Light Energy (In Bulb)Electrical Energy --> Heat Energy (In Bulb)Transformations 2 and 3 happen at the same time, because 3 is a side-effect of the intended transformation 2. I can't think of any other transformations, unless you wanted to consider the process of making the battery, or take the example of an unconventional flashlight.
When energy transformation happen energy is never?
When energy transformations occur, energy is never created or destroyed. Instead, it simply changes from one form to another, such as from potential energy to kinetic energy or from electrical energy to thermal energy. This principle is known as the law of conservation of energy.
What energy transformations happen in a car engine?
In a car engine, the chemical energy stored in the gasoline is converted to thermal energy through combustion. The thermal energy is then converted to mechanical energy as the pistons move and drive the vehicle. Finally, the mechanical energy is transferred to the wheels to propel the car forward.
What energy transformations happen in a solar panel?
Solar panels convert solar energy (sunlight) into electrical energy through the photovoltaic effect. When sunlight strikes the solar panel, it excites electrons, creating an electric current. This electrical energy can then be used to power various devices or stored in batteries for later use.
What happen to the potential energy if 2 protons are brought together?
The potential energy of the protons decreases as they are brought together due to the attractive electromagnetic force between them. As they move closer, the potential energy decreases and it is converted into kinetic energy and other forms of energy, such as thermal energy.
What are 3 transformations and where they happen?
Three types of transformations are translation, rotation, and reflection. These transformations can occur in a plane, on a grid, or in three-dimensional space. Translation moves an object without changing its orientation, rotation turns an object around a fixed point, and reflection flips an object across a line.
What is the study of how matter and energy interact called?
A simple definition of energy; Energy changes and transformations make things happen; Some examples of energy changes making things happen; Stored Solar Energy is the fuel for most living organisms and human made machines; a little bit about Energy and Heat Flow; Energy is a certain something inside stuff (or matter to be more precise) that makes everything happen. When something or somebody moves or jumps or falls or explodes or breathes or thinks or dances or does anything, it's because energy is being transformed.Chemical energy that was "waiting around", doing nothing much but "sitting" in the battery being potential, suddenly starts turning into electrical energy. The new electrical energy, formerly known as chemical, zips through some wires to the electric motor that spins the disc. Now the energy that used to be electrical has become the mechanical energy of the spinning disc's electrical signal from sensors that "read" the spinning disc, travels through a wire to the little speakers in the headphones. In the headphones, the electrical energy that carried the signal, now becomes sound energy (sound Waves study of energy and its changing form is called Thermodynamics.
What is ATP and what role does it play in energy transfers?
ATP IS energy. It makes reactions happen between chemicals that can't happen on their own, like pumping molecules through the cell membrane or helping put together proteins through transcription and translation.
