forms of energy
Activation Energy.
The burning candle releases energy in the form of heat and light, which is then absorbed by the air molecules. These air molecules gain kinetic energy and start moving faster, causing them to push the pinwheel and make it rotate. So, the energy transformation path is: chemical energy (candle) → heat and light energy → kinetic energy (air molecules) → mechanical energy (pinwheel).
An external force is needed to start an object moving. This can be applied through pushing, pulling, or some other method that imparts kinetic energy to the object.
The energy needed to start a car comes from the battery. The battery supplies electrical energy to the starter motor, which then cranks the engine to begin the combustion process. Once the engine is running, it generates its own power to keep the car operating.
No, a source of energy is not needed to start a mechanical wave. Mechanical waves are created by the vibration of particles in a medium, such as air or water, and propagate through that medium without needing a continuous external energy source to sustain them. Once initiated, the wave will continue to move until it encounters an obstacle or dissipates.
The energy needed to start a chemical reaction is called the activation energy :)
A substance that lowers the energy needed to start a chemical reaction is a catalyst.
Activation Energy.
In chemistry it is called a catalyst. Enzymes decrease the activation energy needed to start a reaction.
Activation energy
Yes!
The energy needed to kick start a reaction is called activation energy. It is the minimum amount of energy required for a chemical reaction to occur. It is usually provided in the form of heat or light energy.

Activation energy is the minimum amount of energy required for a chemical reaction to occur. It acts as a barrier that reactants must overcome to form products. This energy is needed to break bonds in the reactant molecules before new bonds can form in the products.
