A simple free-fall problem is a physics problem that involves an object falling freely under the influence of gravity. This means that the only force acting on the object is gravity, and there is no air resistance or other external forces involved.
The formula for calculating the distance of an object in free-fall is d = 1/2 * g * t^2, where d is the distance, g is the acceleration due to gravity (9.8 m/s^2), and t is the time the object has been falling.
The mass of an object does not affect its free-fall. All objects, regardless of their mass, will accelerate towards the ground at the same rate due to gravity.
Terminal velocity is the maximum velocity that an object can reach while falling due to the balance between the force of gravity and the force of air resistance. Once an object reaches terminal velocity, it will continue to fall at a constant speed.
Air resistance, also known as drag, is a force that opposes the motion of an object through air. As an object falls, the force of air resistance increases until it is equal to the force of gravity. This results in the object reaching terminal velocity and falling at a constant speed.
