Free Fall

We head to a football stadium to explain free fall as we work through an example problem finding the maximum height of a thrown object.

Unit 2 Segment E: Free Fall We head to a football stadium to explain freefall as we work through an example problem finding the maximum height of a thrown object.

Premiere Date: August 2, 2018 | Runtime: 00:06:31

## Learning Objectives

-Define free fall.

-Understand that the acceleration due to gravity on earth is 9.8 m/s2 and an object in free fall is constantly experiencing this acceleration.

-Using kinematic equations, be able to calculate the initial velocity, final velocity, displacement, or time elapsed of an object in free fall.

## Vocabulary

free fall - an object in motion only under the influence of the force of gravity.

## Georgia Standards of Excellence

SP1Obtain, evaluate, and communicate information about the relationship between distance, displacement, speed, velocity, and acceleration as functions of time.

SP1.aPlan and carry out an investigation of one-dimensional motion to calculate average and instantaneous speed and velocity. • Analyze one-dimensional problems involving changes of direction, using algebraic signs to represent vector direction. • Apply one-dimensional kinematic equations to situations with no acceleration, and positive, or negative constant acceleration.

SPS8Obtain, evaluate, and communicate information to explain the relationships among force, mass, and motion.

SPS8.aPlan and carry out an investigation and analyze the motion of an object using mathematical and graphical models. (Clarification statement: Mathematical and graphical models could include distance, displacement, speed, velocity, time, and acceleration.)

SPS8.cAnalyze and interpret data to identify the relationship between mass and gravitational force for falling objects.
