Question

the correct answers.
6.1 what is a simple machine? use a complete sentence.

6.2 what is work? use a complete sentence.

6.3 work is done only if an object
6.4 one way work is done is if you use force to change the
an object is moving.

Explanation:

1. For 6.1: A simple machine is defined as a basic mechanical device with few or no moving parts that modifies force or motion to make work easier.
2. For 6.2: In physics, work is the transfer of energy that occurs when a force is applied to an object and the object moves in the direction of the force.
3. For 6.3: By definition, work requires a force to cause displacement of the object in the direction of the force, so the object must move.
4. For 6.4: Work can be done by changing an object's state of motion, which refers to its speed or direction, so the term here is "motion" (or "speed/direction", but motion is the general term).

Answer:

6.1 A simple machine is a basic device with few or no moving parts that makes work easier by changing the size or direction of a force.
6.2 Work is the transfer of energy that happens when a force moves an object a distance in the direction of the force.
6.3 moves in the direction of the applied force
6.4 motion
