3 Video Questions Write the questions in your notebook. Answer them as you watch the video 1. What is speed? 2. What is velocity? 3. What is acceleration? 4. How can acceleration be changed? 5. What pulls the ball down in the video?

4 SWBAT explain how acceleration due to gravity affects the velocity of an object as it falls

5 Determine which statement is the LIE
3 Truths and a Lie Determine which statement is the LIE Gravity is created wherever there is a lot of mass More mass means stronger gravity If you go far enough, you can escape gravity Gravity makes Earth circle the sun

9 Acceleration due to Gravity
Gravity causes objects to accelerate as they fall to Earth Direction of gravitational force is always downward Acceleration due to gravity: ag = 9.8 m/s2

10 Weight Weight: the gravitational force acting on the object
g = 10.0 m/s2 w = mg

11 Weight Calculation Felicia, the ballet dancer, has a mass of 45.0 kg. What is Felicia’s weight on Earth? w = mg

12 Weight Calculation Felicia, the ballet dancer, has a mass of 45.0 kg. What is Felicia’s weight on Earth? w = mg w = (45.0)(10) = N

13 Weight Calculation Felicia, the ballet dancer, has a mass of 45.0 kg. What is Felicia’s weight on Jupiter, where the acceleration due to gravity is 25.0 m/s2? w = mg

14 Weight Calculation Felicia, the ballet dancer, has a mass of 45.0 kg. What is Felicia’s weight on Jupiter, where the acceleration due to gravity is 25.0 m/s2? w = mg w = (45)(25) = N
