Heat energy is the result of the movement of tiny particles called atoms, molecules or ions in solids, liquids and gases
2. True
Electricity is the flow of electrical power or charge. It is a secondary energy source which means that we get it from the conversion of other sources of energy, like coal, natural gas, oil, nuclear power and other natural sources, which are called primary sources.
3. True
This case is sometimes called special relativistic time dilation. The faster the relative velocity, the greater the time dilation between one another, with time slowing to a stop as one approaches the speed of light.
4. True
Materials that allow electricity to pass through them are called conductors. Copper wire is a good conductor. Materials that do not allow electricity to pass through them are called insulators. Plastic is a good insulator.
5. True
The distance covered by an object in a unit of time is called the speed of the object. The formula for speed can be written as the total distance covered divided by the total time taken. Thus, speed equals total distance covered divided by the total time taken to cover the distance.
