Essential Question: How can the motion and causes of motion be calculated, explained and expressed?

At the end of this unit, the students should be able to:

1. Compare and contrast speed and velocity

2. Calculate velocity, distance or time using the velocity formula

3. Distinguish the difference between a positive and negative sign when describing motion.

4. Solve problems using the acceleration formula.

5. Determine what it means for an object to be in free fall.

6. Describe what factors affect the momentum of an object.

7. Calculate the momentum of objects.

8. Explain what part the law of conservation of momentum plays in collisions of objects.

9. Define and explain Newton's three laws of motion in common terms and provide examples for each.

10. Perform calculations relating net force, mass and acceleration of an object to determine if in equilibrium.

11. Define, calculate, and give examples of forces (Contact vs Action-at-a-Distance)

(Frictional, Tension, Normal, Air Resistance, Applied, Spring) vs (Gravitational, Electrical, Magnetic)

12. Explain the difference between mass and weight.

14. Draw a force diagram to represent the forces acting upon an object.

15. Determine what factors affect the amount of gravitational force between objects.

17. Make interpretations about the motion of an object by analyzing the motion of object from a graph (distance vs. time, speed vs. time) (Motion Diagrams)

Identify and convert correct units for the different descriptions of motion. (This is a great checking of understanding!!)
