Question

Frictionisa: (a) acceleration of an object (c) property of an object (b) force (d) velocity of an oiect

Answer 1

For instance, a free-falling object changes its velocity by -9.8 m/s ever second. It is said to have a constant acceleration of -9.8 m/s2. A free-falling object, or any object with an acceleration (whether constant or non-constant) must be experiencing an unbalanced force.
