Study Notes
Free Fall Experiment
- Objective: Determine acceleration due to gravity (g).
- Theory: Objects fall at a constant acceleration (g) near Earth's surface, ignoring air resistance.
- "Free falling" describes objects solely under gravity's influence.
- Displacement equation for constant acceleration: r = Vo t + ½ at².
- Free fall equation (under gravity): Y = Vot + ½ gt².
- Equation for an object dropped from rest (initial velocity 0): Y = ½ gt².
