Presentation transcript:

The Acceleration Due to Gravity Galileo investigated the motion of falling objects. Read about acceleration due to gravity on pages 76-77. He was called the father of science because he believed that experimental results were needed to prove an idea. Objective(s)/SWBAT (Students will be able to): Describe acceleration due to gravity Solve problems involving a the acceleration due to gravity Activities: Drop several objects to describe acceleration due to gravity Example problems related to dropping a ball off of a silo Closure: Questions about gravitation Assessment: Problem set Test Keystones: 3.2.B

Today Students will be able to: Describe acceleration due to gravity. Solve problems involving the acceleration due to gravity. Keystones: 3.2.B

The Acceleration Due to Gravity Demonstrate falling objects by dropping them from the ceiling. Describe g and its units

The Acceleration Due to Gravity The silo is 72 feet tall. How long is the ball in the air? How fast is it going when it hits? What if we throw it? Keystones: 3.2.B

The Acceleration Due to Gravity A marble dropped from a bridge strikes the water in 5 seconds. Calculate the speed with which it strikes and the height of the bridge. Keystones: 3.2.B
