The student's claim that the magnitude of the force of air resistance is proportional to the speed of the object is true because an increase in downward force results in an equal and opposite increase in upward force or air resistance.
The force of air resistance acting on a moving object is known as friction.
An increase in the velocity of an object with time is known as acceleration.
The force on a body is directly proportional to the acceleration of the body. This means that force increases with an increase in acceleration.
According to Newton's third law of motion, force and reaction are equal and opposite.
Hence an increase in the downward force of a falling body results in an increase in air resistance.
