The formula for calculating the final velocity of a falling object is v = u + gt, where v is the final velocity, u is the initial velocity (usually 0 for objects dropped from rest), g is the acceleration due to gravity (approximately 9.8 m/s² on Earth), and t is the time elapsed.
Air resistance, also known as drag, acts in the opposite direction of an object's motion and can decrease its acceleration. As an object falls, it experiences an upward force from air resistance that increases as its velocity increases. Eventually, the air resistance force is equal to the force of gravity, causing the object to reach a constant velocity known as terminal velocity.
Weight is a measure of the force of gravity acting on an object, while mass is a measure of the amount of matter in an object. Weight can change depending on the gravitational pull, while mass remains constant regardless of location.
The acceleration due to gravity is a constant value (9.8 m/s² on Earth), but it can vary slightly depending on the location. For example, on the moon, where the gravitational pull is weaker, the acceleration due to gravity is 1.62 m/s².
The higher the object is dropped from, the greater its velocity will be when it hits the ground. This is because the object has more time to accelerate due to gravity over a longer distance. However, air resistance will also play a role in the object's final velocity.
