Why Do Objects Of Different Masses Fall At The Same Rate?
A-Level and GCSE Physics Question
Date : 02/12/2020
Have you ever Wandered why objects of different masses fall at the same rate? Me too! It turns out it s a really interesting phenomenon.
A video taken by NASA astronauts on the moon showed that a feather and a hammer when in the vacuum of space fell at the same rate? How can this be? (Check bottom of article for the video!)
Well it s all down to good old Newton s forces of motion! The weight of each object is its Mass (Kg) multiplied by its acceleration (g or in the moons case g(m)). Newton s second law states that F=ma for objects in motion.
Equating each objects weight (mg(moon)) as the force in Newton s second law (F=ma). The mass cancels! And acceleration of each object is the same: g(moon)!
Hope you found that interesting! Look at the video of this being shown here: https://m.youtube.com/watch?v=oYEgdZ3iEKA
