What is the transformation of energy in a clock?
The clock now has potential energy. When the alarm rings, the potential energy is converted into kinetic energy and sound energy.
What type of energy transformation takes place during vending of spring of a clock?
Mechanical energy is converted into potential energy during the winding of spring of a clock.
What is the energy transformation of fire alarm?
Chemical energy is released as heat energy in the flames. If the heat energy is detected and sets off the alarm, electrical energy from the battery or power pack is converted to sound energy (bells) or light energy (flashing lights). Making afire alarm.
Does clock use energy?
Modern alarm clocks with built in radios which are Energy Star rated use between 1 and 2 watts of power, while some older models or models which have many extra features can use up to 5 watts. We estimate that a standard alarm clock radio will use 2 watts.
What are the 7 main types of energy?
The Seven Forms of Energy: Mechanical, Heat, Chemical, Electrical Radiant, Nuclear, and Sound. Energy constantly changes form.
What are the 5 sources of energy?
There are five major renewable energy sources
- Solar energy from the sun.
- Geothermal energy from heat inside the earth.
- Wind energy.
- Biomass from plants.
- Hydropower from flowing water.
What kind of energy transformation takes place in human body?
The human body converts energy stored in food into work, thermal energy, and/or chemical energy that is stored in fatty tissue. The energy included in the basal metabolic rate is divided among various systems in the body, with the largest fraction going to the liver and spleen, and the brain coming next.
Does potential energy depend on position?
Potential energy, stored energy that depends upon the relative position of various parts of a system. A spring has more potential energy when it is compressed or stretched. A steel ball has more potential energy raised above the ground than it has after falling to Earth.
