An inclined plane is a plane surface set at an angle, other than a right angle, against a horizontal surface. The inclined plane permits one to overcome a large resistance by applying a relatively small force through a longer distance than the load is to be raised. In civil engineering the slope (ratio of rise/run) is often referred to as a grade or gradient. An inclined plane is one of the commonly-recognized simple machines. Paragraph courtesy of Wikipedia.
Does using a ramp reduce the amount of work needed to raise the object? Explain your answer.
Using a ramp makes lifting easier but it increases the work.
Why do you think people use ramps to work?
Because it is quite a bit easier to use a ramp than lifting something outright.
Describe some examples in everyday life when people use ramps to help them to do work.
Wheelchair ramps, loading ramps, mountain biking trails and walking trails.
I’m doing this unit at a different scool and my teacher ask for much much harder answers, but you made it simple
