Free Fall Velocity Calculator:
Enter the values of acceleration due to gravity, g(m/s2) and time, t(s) to determine the value of free fall velocity, v(m/s).
Free Fall Velocity Formula:
Free fall velocity is defined as the velocity of an object falling under the influence of gravity alone, without any air resistance.
Free fall velocity, v(m/s) in metres per second is calculated by multiplying the acceleration due to gravity, g(m/s2) in metres per second squared and time, t(s) in seconds.
Free fall velocity, v(m/s) = g(m/s2) * t(s)
v(m/s) = free fall velocity in metres per second, m/s.
g(m/s2) = acceleration due to gravity in metres per second squared, m/s2 (9.81m/s2).
t(s) = time in seconds, s.
Free Fall Velocity Calculation:
1.Calculate the velocity of a rock after it has been falling for 5 seconds.
Given: g(m/s2) = 9.81m/s2, t(s) = 5s.
Free fall velocity, v(m/s) = g(m/s2) * t(s)
v(m/s) = 9.81 * 5
v(m/s) = 49.05m/s.
2.Suppose a skydiver reaches a velocity of 98.1m/s during free fall. Calculate the time it took to reach this velocity, assuming the acceleration due to gravity is 9.81 m/s2.
Given: g(m/s2) = 9.81m/s2, v(m/s) = 98.1m/s.
Free fall velocity, v(m/s) = g(m/s2) * t(s)
t(s) = v(m/s) / g(m/s2)
t(s) = 98.1 / 9.81
t(s) = 10s.
