What is the flow of energy in a flashlight?
When the switch of a flashlight is pushed into the ON position, it makes contact between two contact strips, which begin a flow of electricity, powered from the battery. The batteries are connected in such a way that electricity (flow of electrons) runs between the positive and negative electrodes of the battery.
What is the order of energy transformation?
Electric generator (Kinetic energy or Mechanical work → Electrical energy) Fuel cells (Chemical energy → Electrical energy) Battery (electricity) (Chemical energy → Electrical energy) Fire (Chemical energy → Heat and Light)
What is the energy transformation in a light bulb?
electrical energy
Which of the following lists the correct order of energy conversions for a battery operated flashlight?
When the flashlight is switched off, we convert the electrical energy back to chemical energy. Therefore, the energy conversion that occurs in a battery-powered flashlight is chemical energy to electrical energy or electrical energy to chemical energy.
What form of energy is present in the battery?
A battery is a device that stores chemical energy and converts it to electrical energy. The chemical reactions in a battery involve the flow of electrons from one material (electrode) to another, through an external circuit.
What are the 2 main types of energy?
Many forms of energy exist, but they all fall into two basic categories: Potential energy. Kinetic energy.
What are two types of batteries?
Batteries are basically classified into 2 types:
- Non-rechargeable batteries (primary batteries)
- Rechargeable batteries (secondary batteries)
What are the forms of energy with examples?
Examples include nuclear energy, chemical energy, etc.
- Chemical energy. Chemical energy is energy stored in the bonds of chemical compounds (atoms and molecules).
- Electrical Energy.
- Mechanical Energy.
- Thermal energy.
- Nuclear energy.
- Gravitational Energy.
What are the 7 forms of energy?
The Seven Forms of Energy: Mechanical, Heat, Chemical, Electrical Radiant, Nuclear, and Sound.
What are the 4 forms of energy?
The different types of energy include thermal energy, radiant energy, chemical energy, nuclear energy, electrical energy, motion energy, sound energy, elastic energy and gravitational energy.
What are the forms of kinetic energy?
There are five types of kinetic energy: radiant, thermal, sound, electrical and mechanical.

What kind of energy transformation takes place in a human body?
Answer: When a body falls, its potential energy gradually gets converted into kinetic energy. On reaching the ground, the whole of the potential energy of the body gets converted into kinetic energy.
Can kinetic energy of a body be negative?
Common mistakes and misconceptions. Kinetic energy can’t be negative, although the change in kinetic energy Δ K \Delta K ΔK can be negative. Because mass can’t be negative and the square of speed gives a non-negative number, kinetic energy can’t be negative.
When a body is dropped what energy transformation occurs?
kinetic energy
