As per PMBOK the Float is defined as: The amount of time that a schedule activity can be delayed without delaying the early start date of any successor or violating a schedule constraint.

 

It can be calculated in two ways:

Float = Late Start - Early Start

OR

Late Finish - Early Finish

Critical Activities (activities on the Critical Path) usually have a Float of Zero

Float or slack is the amount of time between early start and late start for an activity

e.g. if you can now start an activity (which take one week to complete ) and its OK to complete it within3 weeks without delaying the completion of the project so the float here =2 weeks

There are two types of float: total float and free float. Total float is the amount of time you can delay the earliest start of a task without delaying the ending of the project. 

 

Free float is the amount of time you can delay the start of a task without delaying the earliest start of a successor task.

This is the time duration to which the activity can be delayed without affecting the project duration

I think that the subject needs some details ;-

Free slack or free float is different than Total Float Free Float is the time an activity can be delayed without delaying its subsequent activities Total Float is the time an activity can be delayed without delaying the project completion date.

 

There is no float time for activities on the critical path, that's why they are identified as being critical.

Float, is the time between the planned completion date of an activity in the schedule, and the date where it will become a critical path activity.  Essentially, the extra time allowed in the schedule for an activity, before it will start to affect the overall completion date.

Schedule the project in bottom up approach with realistic time. Make more parallel activity with additional man power. Crash the schedule.
