Verifying Newton’s Second Law

Newton's second law

لقراءة النسخة العربية أنقر هنا.

This experiment was performed in a space shuttle where the gravity is almost zero, so the balls were not affected by any force except the blow of the astronaut. Note that with the same blow (same force) on each ball, the lighter ball accelerates the most, while the heavier one accelerates the least, which complies with Newton’s second law:

    \[\sum\overrightarrow{F} = m \bullet \overrightarrow{a}\]

This equation implies that, for the same net force, the mass and the acceleration are inversely proportional. In other words, for the same net force, as the mass increases, the acceleration decreases, and vice versa.
