Later

2. Describing Motion … Coordinates  Position (displacement)  Velocity
 Acceleration
a) Motion with zero acceleration
b) Motion with non-zero acceleration

3. Velocity Slope is average velocity during t=t2-t1
Slope is instantaneous velocity at t1

4. Acceleration

5. Ex2-3: Engine traveling on rail

7. Kinematics equations for constant acceleration

9. Testing Kinetics for a=9.80m/s2

11. 1-D motions in the gravitational field

12. All objects fall with the same constant acceleration!!

13. Problem: 83

16. Problem 80: A falling stone

18. Problem: 85
Should you stop??

20. Problem 87: Golf on a hill
