1. Chapter-3 Falling Objects and Projectile Motion Outline: Acceleration due to gravity Falling object Projectile motion Overview: Explore how objects move under the influence of gravity close to the surface of the earth.

2. Why objects fall to the ground when released? g = 9.8 m/s 2

3. How to observe the Acceleration Due to Gravity? Galileo’s Method Using a Stroboscope Q2, Q3

4. When you drop objects of different sizes and weights, do they reach the ground at the same time?
