If two forces on an object are balanced (the same Which of the following are size and in opposite true about mass and directions) what happens weight? to the object? If two forces on an object are unbalanced (NOT the same size or in opposite directions) what happens Hooke's Law tells us to the object? that... Weight changes depending on where you are – Mass stays the same It has a constant speed It accelerates in the direction of the bigger force The extension of a spring will double if you apply double the force |
