directly proportional
as one amount increases, another amount increases at the same rate
indirectly proportional
when the value of one quantity increases with respect to a decrease in another or vice-versa
directly proportional
The greater the force that is applied, the greater the acceleration
indirectly proportional
If the same force is applied to an object with a large mass, it will have a lesser acceleration
