An invention is the creation of a new material or we can say that the action of inventing something new is called invention.

Wheel:

Machines:

In the ancient time or past we had very problems in the farm lands says food take so much time to grow , ploughing etc . But because of these machines ( Tractor ) we can easily plough and the food gets ready in shorter period of time . Also these machines are used everywhere . We use air conditioners to keep our room cool , we use room heaters to keep our room hot . We use vehicles to travel long distances.See in the second image.

Telephones/Mobiles :

Telephones are also a great invention of the men . We can communicate with our relatives or friends who are living far away from us . These telephones also play a crucial role in the business . We can save our time without travel a long distances with the help of mobiles/telephones . See in the third image .
