Question

name: _ date: _ forms of energy answer sheet (version 1) questions 1. what is energy? what can an object with energy do? 2. briefly describe the different forms of energy in the table below. energy form definition mechanical motion or position radiant electrical sound thermal chemical 3. how does the amount of thermal energy change with temperature? 4. what is the difference between static and current electricity? 5. which forms of energy are vital to the survival of living things? justify your answer

Explanation:

1. Energy is the ability to do work. An object with energy can cause change, such as making things move, change shape, or heat up.
2. Radiant: Energy carried by electromagnetic waves like light. Electrical: Energy due to the flow of electric charges. Sound: Energy produced by vibrating objects as waves. Thermal: Energy related to the motion of particles in a substance. Chemical: Energy stored in chemical bonds.
3. The amount of thermal energy increases as temperature increases because higher - temperature substances have faster - moving particles with more kinetic energy.
4. Static electricity is the build - up of electric charges on a surface, while current electricity is the flow of electric charges through a conductor.
5. Radiant energy (from the sun for photosynthesis), chemical energy (in food for metabolism), and thermal energy (to maintain body temperature) are vital for the survival of living things.

Answer:

1. Energy is the ability to do work. An object with energy can cause change.
2. Radiant: Energy carried by electromagnetic waves. Electrical: Energy from electric charge flow. Sound: Energy from vibrating objects as waves. Thermal: Energy from particle motion in a substance. Chemical: Energy stored in chemical bonds.
3. Thermal energy increases with temperature as particles move faster.
4. Static electricity is charge build - up on a surface; current electricity is charge flow through a conductor.
5. Radiant, chemical, and thermal energy are vital for living things' survival.
