Sagot :
Answer:
If we have no gravity:
- Humans and other objects will become weightless without gravity.
- The atmosphere would disappear into space, the moon would collide with the earth, the earth would stop rotating.
- we would all feel weightless, the earth would collide with the sun, and as a consequence.
If we have no Friction:
- If there was no friction everything would slide to the lowest point.
- If there is no friction we can not walk,run.
- It would be impossible to climb up anything.
