Question

explain why the effect of blowing on the golf ball and table tennis ball were different even though they were both being blown with the same force.

Explanation:

The acceleration of an object depends on its mass according to Newton's second - law ($F = ma$). A golf ball has more mass than a table - tennis ball. When the same force is applied, the table - tennis ball, with less mass, will have a greater acceleration and thus a more noticeable response to the blowing force compared to the golf ball which has more inertia due to its greater mass.

Answer:

The golf ball and table - tennis ball respond differently when blown with the same force because the golf ball has more mass and thus more inertia, resulting in less acceleration compared to the less - massive table - tennis ball according to Newton's second law ($F = ma$).
