Question

many simple machines enable people to use
____ force over a ________ distance.
→ for example, consider climbing a hill. we
can climb it in two ways. we can climb
________ the steep side of the
hill. the ______________ covered is
__________, but we’ll be exerting more
force with each step. the other way is to
walk on a ____________ road that leads
up the hill. here, we’ll walk a __________
distance, but we’ll be exerting ______
______ with each step.

Explanation:

This question is about simple machines and the trade - off between force and distance, which is a concept in Physics (a subfield of Natural Science).

1. For the first two blanks: Simple machines allow us to use less force over a greater distance. So the first blank is "less" and the second is "greater".
2. When climbing the steep side of the hill: We climb "straight up" the steep side. The "distance" covered is "shorter", but we exert more force.
3. For the road up the hill: It's a "gentle" (or "sloped") road. We walk a "greater" distance, but exert "less force".

Answer:

1. less; greater
2. straight; up; distance; shorter
3. gentle (or sloped); greater; less; force
