im doing an experiment that is measuring the force of a hanging object from a string. in the experiment we are also measuring the force of the object in free fall, so we hold the object and let it fall and the force is measured. which one should produce a greater force, or should they be similar forces?
there is also a question that asks
1. on what depends the magnitude of the force in the experiment, if an object falls down and is stopped by a string or rubber band? write down your observations.
