What causes acceleration?

 

[Lesegp]

What causes acceleration

A force applied to an object at rest causes it to accelerate in the direction of the force.

A force applied to an object at rest causes it to accelerate in the direction of the force.

And what force(s) act on the coin after it is dropped?
