Calculating the Falling Speed after 12 Seconds of Free Fall

Understanding Free Fall

Free fall is a term used in physics to describe the motion of an object falling under the sole influence of gravity. When an object is in free fall, it is accelerating downward at a constant rate of 9.8 m/s².

Calculating Falling Speed

Given data:
Acceleration due to gravity (g) = 9.8 m/s²
Time (t) = 12 seconds Free fall formula:
v = -gt
where:
v = velocity of free fall
g = acceleration due to gravity
t = time Putting the given values into the formula:
v = -gt
v = -12 × 9.8
v = 117.6 m/s Therefore, the falling speed after 12 seconds of free fall is 117.6 m/s.

you jump off a cliff and accelerate at 9.8 m/s^2 due to gravity. How fast are you falling after 12.0 seconds?

By the speed of 117.6 m/s you falling after 12.0 seconds.
