Understanding Free Fall Physics in Classroom Agenda
Explore the physics of free fall in a classroom setting through a diverse agenda covering warm-up activities, homework check, lab work, test review, and worksheets. Discover concepts like gravity, acceleration, velocity, and distance fallen using engaging visuals and practical examples. Gain insights into the impact of air resistance on falling objects and differentiate between acceleration and time in free fall scenarios.

Review Quiz Multiple Choice
Free Fall Why does an object fall to the ground when dropped? GRAVITY Gravity pulls objects towards the Earth at an acceleration 9.8 meters/sec/sec (m/s2).
Free Fall: How Fast Elapsed time the time that has passed since the beginning of the fall. In free fall, an object accelerates at a rate of 10 m per second every second
Free Fall: How Fast To calculate velocity in free fall: velocity = acceleration X time or v=gt Remember: g= acceleration due to gravity
Free Fall: How Far How fast something falls is different from how far it has fallen
Free-Fall: How Far? To calculate distance fallen: distance=1/2g X time 2 or d=1/2gt2
Elephant VS Feather With no other resistance, they both fall with the SAME ACCELERATION: 10 m/sec/sec
But we all know the elephant would land first. Why? Answer: AIR RESISTANCE Air resistance alters the motion of falling objects by adding additional forces.
