**Content Objectives:** Students will demonstrate application of the Universal Law of Gravitation- Relationships by completing a structured practice and chapter 13 summary.

**Language Objectives: **Students will write to explain the Universal Law of Gravitation using the big idea and formula on a structured practice and chapter 13 summary.

**Bell Work:**

The motion of an object can be represented by a position-time graph like the Figure below. In this type of graph, the y-axis represents position and the x-axis represents time. A position-time graph shows how far an object has traveled from its starting position at any given time since it started moving and the velocity of the moving object is represented by the slope, or steepness, of the graph line.

1.Which line represents a faster speed?

a.Line A because it is more shallow than Line C

b.Line A because it is steeper than Line C

c.Line C because it is steeper than Line B

d.Line B because it is a horizontal line

- Which object has the greatest speed?
- Object A b. Object B
- Object C d. Not enough information

**Exit Ticket:**
