Free Falling

	Free Fall
	Motion of an object is affected by gravitational force (no other forces - air resistance, friction)

Gravitational acceleration, \(\text{g}=9.81\text{ ms}^{-2}\)
- In calculation, when object falls down, value of g is positive (+), when obejct is thrown up, the value of g is negative (-).
