... ever notice that back packers, mountain climbers, all ways pack in the lightest way possible and do not carry any more weight the they have to. Less weight makes it easier...
Examples:
- Take your self and run the 50yd dash. See what you time is.
- Now put on a 50lbs back-pack and run the 50yds.
- Now add another 50lbs to the pack and run the 50yds. How much slower was your time and how much harder was it to run?
- Add another 50lbs to the pack and run again. Are you times getting worse?
- Again add another 50lbs, so now you have added 200lbs to your track weight. Are your times getting worse?
Example:
- Imagine if you had to power the car down the 1/4 mile.
- Take a 2500lb crx and push it down the 1/4 mile.
- Now remove 500lbs and push it again down the 1/4 mile.
- Remove another 500lbs and push it again. It it getting easier to push/better times?
- Again remove 500 more lbs and push again...now you know how your engine feels.
The point to my post is a heavier object takes more force/power/energy to move it. Unlike a lighter object take less force/power/energy...it it basic physics people.
