Is there a "real" simple machine that has an efficiency of 100%?

Physics
1 answer:
VARVARA [1.3K]3 years ago
8 0

Answer:

NO

Explanation:

No, a machine cannot be 100% efficient. This is due to the movement of the moving parts siding against each other and causing friction. This friction is the one that creates heat and causes wear and tear between moving ports f the machine hence making the machine to decrease in efficiency with time

According to Newton's third law, if you push on a wall, the wall ?
Lady bird [3.3K]

The wall will push back, in exactly the opposite direction, and with
exactly the same size force.

That's why the net force on the palm of your hand is zero, and that
in turn is the reason that your hand doesn't accelerate.

If you keep increasing the strength of your push, then eventually you
exceed the force that the wall is capable of delivering.  Then the wall
crumbles and falls, your hand accelerates in the direction you're pushing,
and the crowd goes wild !
