-The picture goes to Activity 2
-Its due today please help

Activity 1: Journal: What evidence would you need to support the idea
that the force required to lift a load is directly proportional to an object's
weight?

Activity 2: Look at the photo and answer the questions that follow.

-Ramps are considered which type of simple machine?

-What is the purpose of
this type of simple machine?

Activity 1: Since the only forces apposing the upward movement of the load are gravity and air resistance the formulas of which can both be solved with weight then with constant variables for gravity and air, effort IS directly proportional to weight.

Activity 2:

Inclined plane.

to make lifting easier; raising or lowering a load.

Explanation:

hope this helps.

i believe the answer is a.
