In a frictionless environment, when three blocks weighing 20 kg each are pushed with a force of 10 N, all blocks will move to the right, receiving the full 10 N force. The person applying the force will experience a reaction force of 10 N in the opposite direction. This principle remains consistent even when the masses increase to 1 million kg, although the acceleration will decrease due to the higher mass. Understanding these dynamics is crucial for applying Newton's laws of motion effectively.

caljuice said:If there are 3 blocks weighing 20 kgs each and placed next to each other on a frictionless floor, and I exert 10 N, all 3 blocks will still move right? Do all the boxes receive a 10N push since there is no friction to reduce the force as it transfers? But do I only get pushed back 10N due to reaction force? Finally do the same concepts apply if the masses are 1million kgs? Thanks!
