Any force that is more than 50 pounds will lift a 50-pound object.
The greater the force is, the greater the object's upward acceleration,
and the sooner the object will reach any given height.
Any force that is more than 50 pounds will lift a 50-pound object.
The greater the force is, the faster it will lift the object.

When you pick things up, you apply lift. This is as opposed to something like levers, which still lifts something, but usually involves you applying downward force.
Compressible fluid force opposes lift. Lift is the upward force due to the fluid flow around an airplane wing. Weight is a downward force caused by gravity which opposes lift.
'Lift' is an upward force on a plane. Upward force on a bird's wings is also called 'Lift'.
Assuming the dumbbell is suspended at a constant height from the ground and not moving you are exerting 89 Newtons (N). Force (N) = Mass (kg) x Acceleration due to gravity (9.8067 m/s2) 20lb = 9.072 kg 9.072 x 9.8067 = 89 N Leigh

There is not a better brand of dumbbell to use. Any brand that is in your budget is best. You will need to easily be able to lift them and they shouldn't hurt your hands.
Hmm well lets see at my age of 14 I can about lift a 20 25 Pound dumbbell with a single arm then again I am no body builder so Im guessing maybe if you worked out a bit a few push-ups here and there probably a 15 or 20 pound dumbbell but just a guess
Isotonically - The load your are lifting is equal to or less than the force generated by your muscle. Your muscle shortens when it contracts allowing you to lift the dumbbell.
Yes, if they want too. It's perfectly fine.

By using leverage, it allows you to lift a 1 or 2 ton car. Have you tried lifting a car by hand without a jack? And you DO need to lift the car to change a tire.

A super set is when you have two different lifts and you replace your rest period with a set of the second lift For example, a lift you could be doing can be like dumbbell bench and dumbbell row where the sets would be like bench, row, bench, row, bench, row
If you have a man submerged up to his neck in corn and you want to know how many pounds of force it will take to lift him out, information about the volume, weight, mass, density would be needed in order to calculate the force needed.
It would require (3 X 10)/15 = 2 lb to lift the 3 lb weight. Actually, something a little greater than that. 2 lb is the force to balance it. (Obviously, the lever "has" no force. It requires the force to lift the weight.)
