Show that newton's second law of motion is the real law of motion
Answers
according to the 2nd law of motion in the absence of external force, momentum remains conserved.
the 3rd law of motion is proved.
therefore, newton's 2nd law of motion is the real law of motion.
Explanation:
☞Rockets can propel themselves through the nothingness of space because of two fundamental laws of physics: Newton’s Third Law and the Conservation of Linear Momentum.
☞Both ideas are essential to understanding how nearly everything in the universe moves.
☞When an ice skater takes off from a dead stop, she digs her blade into the ice and the ice pushes back with an equal and opposite force, sending her gliding across the rink.
☞When a cannon is fired, the cannonball goes hurtling through the air while the cannon recoils backward in response.
☞Both of these principles stem from the same general idea: that the universe likes to keep everything in balance.
