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.

What energy transformation iis needed to start a helicopter?
To start a helicopter, the energy transformation needed involves converting chemical energy stored in the fuel into mechanical energy. This is achieved by the combustion of fuel in the engine, which creates the necessary rotational motion to start the helicopter's rotor blades.
Physics in electrical motor what kind of energy does it start with and what kind does it end with?
An electrical motor starts with electrical energy supplied by a power source. This energy is converted into mechanical energy as the motor turns and does work, such as driving a fan or a conveyor belt.
What energy is the energy needed to start a reaction?
Activation Energy.
What type of energy does a hand drill start with and what type of energy does it produce?
A hand drill typically starts with mechanical energy in the form of the motion you apply to turn the crank. When you use the hand drill to bore into a material, it produces mechanical energy through the rotation and movement of the drill bit.
How is wind energy transformed into kinetic energy?
The energy in the wind is kinetic, it is due to a mass of air moving at a certain speed. Wind energy is transformed into mechanical energy through the blades of the wind turbine, and the mechanical energy is then transformed into electrical energy in a generator driven by the blade axis.

What are the source mechanical energy?
A form of chemical energy such as in the combustion process to start the mechanical process (energy) of a car engine. A battery uses chemical energy to power things like clocks or the A/C in your car. A person moving an object is displaying mechanical energy by moving the object, yet they themselves are powered by the chemical energy in the nutrients they take in when they eat.
What is needed to start a fire?
Fuel, Oxygen and a heat source. Fuel, Oxygen and heat are everywhere why is the whole earth not on fire? because it is not Heat but a source of ignition that is needed.
What do chemist call the energy needed to start a reaction?
The energy needed to start a chemical reaction is called the activation energy :)
Which is the best description of activation energy?
The amount of energy needed to start a chemical reaction. Source: Biology class

What substance lowers the energy needed to start a chemical reaction?
A substance that lowers the energy needed to start a chemical reaction is a catalyst.
What energy is the energy needed to start a reaction?
Activation Energy.
What creates mechanical energy?
A form of chemical energy such as in the combustion process to start the mechanical process (energy) of a car engine. A battery uses chemical energy to power things like clocks or the A/C in your car. A person moving an object is displaying mechanical energy by moving the object, yet they themselves are powered by the chemical energy in the nutrients they take in when they eat.
What effect does an enzyme have on a activation energy needed to start a reaction?
In chemistry it is called a catalyst. Enzymes decrease the activation energy needed to start a reaction.
It refers to the amount of energy needed to start the reaction?
Activation energy
Is Activation energy is the energy needed to start a chemical reaction?
Yes!
