Question
Freefall is the motion that an object undergoes when the only force acting on the object is the force of gravity.
Typically the vertical direction is labelled by the y coordinate and the constant acceleration equations of motion are simply modified
(i.e. just replace a with y).
v = vo + at
y – Yo = vot + ať?
y – Yo = } (vo + v) t v? = v3 + 2a (y – yo)
Which of the following statements about freefall motion are correct?
If an object in freefall has an downwards velocity of 10 m/s then the acceleration of gravity in the constant acceleration equations of motion is
a = -g = -9.8 m/s².
If an object in freefall has an upwards velocity of 10 m/s then the acceleration of gravity in the constant acceleration equations of motion is
a = -g = -9.8 m/s².
If the Y-coordinate system is chosen to point upwards (i.e. Y increases when moving up), then the acceleration of gravity in the constant
acceleration equations of motion is a = -g= -9.8 m/s².
For an object to be in freefall then it must be falling, i.e. moving in a direction towards the Earth.
