Unit:
Forces and Motions 7.P.1.1-7.P.1.4
Common Core and/or Essential Standards:
1. Understand motions.
2. The effects of forces on motion.
3. Graphical representations of motion.
Understandings: Students will understand that…
Motion behaves according to laws. (Newton’s Laws)
An objects motion can be described by its position, direction, and
speed.
Students will understand the effects of balanced and unbalanced
forces.
Creating and interpreting graphs to show changes in position, time,
speed and variable motion.
Balanced and unbalanced forces effect movement of objects.
