I'm 70 yrs old and started swimming last August. I'm swimming with an awesome Masters team.
I've lost quite a bit of weight, still have 20lbs to go; I'm getting there but have two questions:
1: Am I pulling an extra 20lbs with each pull? At first it seems an obvious yes, but I wonder if being in water makes it different.
2: When the weight is off will it be easier for me to get and stay underwater? - I'm having a tough time pushing off the wall streamline underwater.
odd questions I know, but I'd really appreciate it if anyone can tell me?
Thanks,
Pam
F does = ma, and in a vacuum m would be the only thing affecting a. As noted above, in a fluid there are other forces affecting a that are much more important than weight. Which is going to take more force to accelerate in the water a 10 lb surfboard or a 5 lb open parachute?
Of course, Allen, but I just felt like I need to add to what Sojerz' said. Forces act in opposition. If you aren't accelerating yourself by applying a force against the water drag doesn't enter the equation. Propulsive forces accelerate you, drag forces decelerate you.
