Answer:

Correct: A staircase is an example of an inclined plane.

The force exerted by a machine on an object that’s lifted or moved is the output force.

All machines have a mechanical advantage of 1 or more than 1.

Incorrect: All simple machines have a fulcrum.

When a person swims through water, no work is done.

A machine’s power depends on how fast the machine is able to do work.

Explanation:

Correct:

  • A staircase is an example of an inclined plane.
  • The force exerted by a machine on an object that’s lifted or moved is the output force.
  • All machines have a mechanical advantage of 1 or more than 1.

Incorrect:

  • All simple machines have a fulcrum.
  • When a person swims through water, no work is done.
  • A machine’s power depends on how fast the machine is able to do work.

What is work ?

"Work is the transfer of energy by a force acting on an object as it is displaced." The work that a force does on an object is the product of the magnitude of the force, times the magnitude of the displacement, times the cosine of the angle between them.

What is force ?

"The push or pull on an object with mass that causes it to change its velocity." Force is an external agent capable of changing the state of rest or motion of a particular body. It has a magnitude and a direction.
