Week 14
Topic: Friction and Gravity.
Students will be able to:
Describe the friction, and identify factors that determine the friction force between two objects.
Identify the factors that affect the gravitational force between two objects.
Explain why objects accelerate during free fall.
Essential Question:
How does distance affect gravity? How did Newton do it?
This week the kids discover how mass, distance, weight, acceleration, speed, and gravity are all related.
Key Terms:
friction
weight
gravity
