Gravity
Acceleration of a falling object is caused by the force of gravity. Gravity is a force that pulls objects towards the center of the Earth, causing them to accelerate downward at a rate of 9.8 m/s^2.
Assuming that there are no other forces on the object, the force that causes the acceleration of a falling object is the gravitational force (attractive force that exists between two masses). In problems, this assumption is usually used.However, in Force = mass*acceleration it is important to remember it is net acceleration and net force. Thus, for an object falling in real life the acceleration is caused by the gravitational force and a drag force which results from the object moving through the air. You have to take into account all the forces on the object.
Gravity
Acceleration is caused by a change in an object's velocity, either in speed or direction. This can occur due to the application of a force to the object, such as gravity or a push or pull from another object.
You can calculate the force of a falling object using the formula: Force = mass x acceleration due to gravity. The acceleration due to gravity on Earth is approximately 9.81 m/s^2. Simply multiply the mass of the object by 9.81 to find the force of the object falling.
-- The rate of acceleration of an object on the moon is(the net force on the object)/(the object's mass) .-- If the object is falling, with nothing but the force of gravity acting on it, thenits acceleration is 1.623 m/s2 (compared to 9.807 on Earth).
the acceleration of gravity is 9.8 m/s
When an object is falling and the force of gravity is the only force acting on it, the object experiences a constant acceleration towards the Earth due to gravity. This acceleration is approximately 9.8 meters per second squared near the surface of the Earth.
Three things that can be caused by an unbalanced force are acceleration of an object, change in velocity of an object, and deformation or breakage of the object.
If an object is falling at a constant velocity, then the net force acting on it is zero. This means that the force of gravity pulling the object downward is balanced by an equal and opposite force. The object will continue to fall at a steady speed without accelerating.
When a falling object reaches its terminal velocity, its acceleration becomes zero. The downward force of gravity is balanced by the upward force of air resistance, resulting in no overall acceleration.
Force is directly proportional to acceleration, according to Newton's second law (F = ma), where F is the force applied to an object, m is the mass of the object, and a is its acceleration. Gravity is a type of force that can cause acceleration, as in the case of free-falling objects where the force of gravity causes the object to accelerate towards the Earth.
