What is Free Fall Motion?
Free fall is the motion of an object where gravity is the only force acting upon it. In real-world scenarios, air resistance also plays a role, but in ideal free fall, we neglect air resistance to study the pure effects of gravity. All objects in free fall near the Earth's surface accelerate downward at the same rate, regardless of their mass, as famously demonstrated by Galileo.
Gravity and Acceleration
The acceleration due to gravity, denoted as g, is approximately 9.8 m/s² near Earth's surface. This means that in free fall, an object's velocity increases by 9.8 m/s every second. The acceleration is constant and always directed downward toward the center of the Earth.
Energy Conservation
In free fall, mechanical energy is conserved. As the object falls, potential energy (mgh) decreases while kinetic energy (½mv²) increases by exactly the same amount. The total mechanical energy remains constant throughout the fall.
Real-World Applications
Skydiving: Understanding parachute deployment and terminal velocity. Sports: Basketball shots, javelin throws, and diving. Engineering: Design of elevators, escalators, and amusement park rides. Space Science: Orbital mechanics and spacecraft trajectories.
Problem-Solving Strategy
Step 1: Identify known quantities (h₀, v₀, t). Step 2: Determine which formula to use. Step 3: Substitute values into h(t) = h₀ - ½gt² + v₀t or v(t) = v₀ - gt. Step 4: Calculate and check units. Step 5: Verify energy conservation.
