This document contains two similar worksheets about forces and simple machines. Worksheet 1 asks about forces causing objects to speed up or slow down, like friction on a snowball or gravity on a parachute. It also asks about friction causing a bear to fall. Worksheet 2 asks similar force-related questions and provides diagrams of simple machines to identify. Both worksheets ask students to unscramble letters to reveal force terms and define vocabulary.
