Question

How does a free-body diagram tell you about the acceleration of an object? Explain.

Answer 1

We know, acceleration is the force due to gravity, so as object is falling (free-body), acceleration would be negative (as directions are opposite), and if the body is on earth it's magnitude will be 9.8 m/s²

Hope this helps!

Answer 2

A free-body diagram shows the vectors for all the forces acting on the body. The resultant vector found by summing all the individual vectors represents the net force.
