Answer:
the force of gravity causes it to accelerate
Explanation:
An object which is dropped from a certain height has an uniformly accelerated motion, with constant acceleration of 9.81 m/s^2, downward. This acceleration is due to the force of gravity, which pushes the object downward. As a result of the force of gravity, the object will have an acceleration, as stated in Newton's second law:
\(F=ma\)
where F is the force exerted on the object, m is the mass of the object and a is its acceleration.
