Gravity Unveiled: The Science Behind Free Fall & Acceleration
This PowerPoint explores the concept of free-fall motion and the acceleration due to gravity, building on previous lessons in kinematics. It begins by debunking early misconceptions about falling objects, showing how Galileo proved that all objects accelerate at the same rate regardless of mass (ignoring air resistance). His ramp experiment demonstrated that falling motion is equivalent to rolling down an inclined plane, confirming the constant acceleration equation (y = 1/2 gt²).
The presentation also covers:
Velocity and acceleration in free fall, explaining how velocity increases linearly over time.
Objects thrown vertically, detailing how upward motion decelerates at -9.8 m/s² before reversing direction.
Mathematical modeling of falling objects, including formulas for position and velocity as functions of time.
Real-world applications, such as predicting motion in gravitational fields.
