1) How much force will it take to make a 500 pounds barbell move?
2) How much force then after it is "in motion" will it take to keep it moving at the same speed?
3) How much force will it take to then cause it to accelerate once in motion?
My answers, am I right or wrong?
1) If you load a barbell with 500 pounds and apply 500 pounds of force in an attempt to dead lift it, you will not move the 500 pounds, you need to apply 500.1 pounds to move the barbell.
2) But once it's moving at a constant speed, you need to apply 500 pounds of force only, and it will keep moving at this speed.
3) 500.2, 500.3 and 500.4 to keep it accelerating. If the force is reduced, the barbell will decelerate, if it is increased the car will accelerate, and if it matches, or equals the force, it will be in balance, or equal.
