Inversely proportional means that one variable goes up while the other goes down. Directly proportional means that both variables increase or decrease at the same time. ex: The volume of a gas at constant pressure is inversely proportional to gas pressure, thus this means that as pressure increases, the volume of the gas will decrease. ex: The volume of a fixed amount of gas is directly proportional to absolute pressure, thus this means that when you heat a gas the volume also increases.

Directly proportional relationship is F=ma, F is directly proportional to a. Inversely proportional relationship is v=r/t, v is inversely proportional to t.

Force is directly proportional to mass provided the acceleration is constant.

Directly. That's why you can't move a car by blowing on it.

Directly proportional, at pressure and temperature constant.

Disproportional.If instead you're looking for the antonym of directly proportional, that would be inversely proportional.

No, an object's acceleration is inversely proportional to an objects mass.

Generally, if y increases as x increases, this is a hint that the quantity is directly proportional, and if y decreases as x increases, the relation might be inversely proportional. However, this is not always the case. x and y are directly proportional if y = kx, where k is a constant. x and y are inversely proportional if y = k/x, k is constant. This is the best way to tell whether the quantities are directly or inversely proportional.
