Types of Rocks and Fossils - Missed Questions

Simple machines can make work easier by reducing the input force needed to move an object. However, there is a trade off for decreased input. What is the trade off?

• The distance the object is moved is increased.

• The distance the object is moved is decreased.

• The amount of work is increased.

• The amount of work is decreased.
