Q:

# What Is Newton's Law of Air Resistance?

A:

The concept of air resistance is related to Newton's second law of motion, which describes acceleration and force. Air resistance is a significant factor in how fast an object falls, according to this law.

The example of the "elephant and the feather" is often used in classrooms to demonstrate how Newton's law applies to air resistance. If dropped in a vacuum, the elephant and the feather fall at the same rate. Objects falling in Earth's environment, however, are acted upon by gravity and air resistance, which causes the elephant and feather to fall at very different rates. In the absence of only air resistance, they would hit the ground at the same time.

Riding a bike is an example of Newton's third law of motion because the force needed to pedal a bike forward, which is the force that the tire exerts on the ground, is equal to the force of the ground pushing against the tire. The real-world example of riding a bike can also be used to demonstrate Newton's first and second laws of motion.

Some force and motion experiments include dropping two objects of different masses from the same height to demonstrate Newton’s law of acceleration, and the terminal velocity experiment to demonstrate the interaction of the effect of drag or resistance on acceleration. Two objects with different masses dropped from the same height reach the ground at the same time.

Friction makes the observation of Newton's first law difficult because it is an unseen force that interferes with the law. Newton's first law states that an object in motion continues its motion unless acted on by an unbalanced force. Friction is a contact force that opposes motion; an object in motion in a real-world scenario eventually slows down due to friction, even though it seems to slow down by itself.
