Question

Tas watches as his uncle changes a flat tire on a car. His uncle raises the car using a machine called a jack. Each time his uncle pushes down on the jack handle, the car rises up. Tas sketches the jack and labels it using the symbols F, to represent force, and d, to represent distance. He uses large and small letters to compare the sizes of the forces and distances. Which set of labels is correct for the side of the jack that Tas’s uncle pushes on?

Answer 1

The correct label would be: small f and capital D.

The car jack is an example of a machine, which is defined as anything that a person can use to make the exertion of force easier. So with the small force he exerts on the jack, the distance that the car is lifted up increases.

Answer 2

Answer

The answer is small f and large D.
