Question

Show that newton's third law of motion is constant in his 2nd law

Answer 1

Third law

action = - reaction

Second law
F=ma

so considering that the forces acting on an object are constant, the system will keep itself in a constant state, hence uniform acceleration or no acceleration

Answer 2

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.
