The answer is mass and acceleration
The answer is
-Small f and large D.
The explanation:
-when 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
.
and People needs help of machines to increase their force. People cannot lift a car without a machine. Using the leverage or hydraulic principles the machines increase your force.
If you use a large leverage you execute a large movement with little force and as result the other side will move small distances with a greater force.
South it is the same direction the car is already moving
Rolling friction is less than sliding friction
Any large factory that takes multiple machines to manufacture a singular product.
