The forces that act on the blocks as they descend the ramp are;
- Weight of the block
- Reaction force on the block
- Applied force
- Frictional force
<h3>What is force?</h3>
Force is that which is able to produce a push or a pull. Force causes an object to move from one point to another. For the body that is moving down the ramp there are four forces that act on it;
- Weight of the block
- reaction force on the block
- Applied force
- Frictional force
The weight of the block moves it downwards, the reaction force moves the block upwards, the applied force moves the block forward while the fricional force opposes the forward movement of the block.

Answer:
Compare Silicon and Sulfur on the basis of their properties, attributes and periodic table facts. Compare elements on more than 90 properties. All the elements of similar categories show a lot of similarities and differences in their chemical, atomic, physical properties and uses. These similarities and dissimilarities should be known while we study periodic table elements. You can study the detailed comparison between Silicon vs Sulfur with most reliable information about their properties, attributes, facts, uses etc. You can compare Si vs S on more than 90 properties like electronegativity , oxidation state, atomic shells, orbital structure, Electronaffinity, physical states, electrical conductivity and many more.
