Acceleration of Gravity and Newton's Second Law
Calculate weight, velocity, and distance traveled for free-falling objects using Newton's Second Law and gravitational acceleration.
Acceleration of Gravity and Newton's Second Law
Newton's Second Law for gravity force (weight) is expressed as:
W = m × g
Where:
- W = Weight/Gravity force (N)
- m = Mass (kg)
- g = Acceleration of gravity (9.81 m/s² or 32.174 ft/s²)
Free Falling Object Calculations
Velocity: v = g × t
Distance: s = ½ × g × t²
Time to fall: t = √(2s / g)
