Explanation:
gravitational force or gravity is the force of attraction between objects that have mass.
frictional force is the forec that opposes motion (movement) when two surface are in contact. (acts in the opposite direction of motion)
so to sum it up,
- gravtional force is the force of attraction between objects that have mass.
- objects on the earth have weight because of gravitational force between them and the earth.
frictional force
- oppose motion
- slow down and stop moving objects and;
- produce heat
hope it helps :)
Answer:
The difference between the greenhouse effect and global warming is that the greenhouse effect is when the sun’s energy reaches the earth’s atmosphere and some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases. Global warming is the unusually rapid increase in Earth’s average surface temperature. The difference is that that the green house effect is a natural process that happens constantly and global warming is a change due to earth’s climate causing it to heat up. Carbon monoxide affects global warming by trapping the gasses in the atmosphere which causes an increase in temperature. For an example, three sources of atmospheric carbon dioxide is car fumes, factory fumes, and coal.
