What is Newton's second law of motion?

It relates acceleration to force applied to a mass.

How is weight defined?

Weight is the gravitational pull on a mass.

Friction opposes motion by creating resistance.

Mass determines the resistance to motion change.

Terminal velocity is a constant speed during free fall.

Newton's second law of motion links acceleration to force, showing that applying force to an object results in acceleration, with an inverse relationship between mass and acceleration.
Friction, influenced by surface characteristics and contact area, opposes motion by creating resistance, while mass determines inertia, affecting an object's resistance to changes in motion.

Newton's second law of motion relates acceleration to force, where force applied to a mass results in acceleration.
The relationship between mass and acceleration is inverse; as one increases, the other decreases.
Weight is defined as the gravitational pull on a mass, varying based on the planet's mass.
Friction opposes motion due to microscopic bumps on surfaces acting like velcro, creating resistance.
Friction levels depend on the objects' surfaces and their surface area in contact.
Mass determines inertia, the resistance to motion change, with more mass equating to more inertia.
Mass is measured in kilograms, while weight is the force of gravity acting on a mass, measured in newtons.
Newton's formula states that acceleration is directly proportional to force and inversely proportional to mass.
Acceleration can be calculated as force divided by mass or force equals mass times acceleration.
Inertia explains why objects of different masses fall at the same rate, as gravity and inertia balance out.

Motion and friction cause microscopic stoppage, slowing down objects unless in a frictionless environment like space.
Falling in the air involves air molecules acting as a wall, creating air friction that opposes gravity's pull.
Air friction slows down falling objects, preventing them from reaching maximum speed in a non-vacuum environment.
Terminal velocity is reached when gravity is balanced by air resistance, causing a constant speed during free fall, as demonstrated by the Apollo 11 moon experiment with a feather and a hammer.
