3.
the force of gravity produces acceleration in all objects and this is known as acceleration due to gravity.

a. tethered
b. plastic
c. freely falling
d. wooden

The force of gravity produces acceleration in all freely falling objects and this is known as acceleration due to gravity.

Option C

Explanation:

When the falling of any object is due to action of gravity then it is called freefalling object which is explained in newton's second law of motion. The "acceleration due to gravity" of "free falling object" is constant and is given by 9.8m/s and is denoted as "g". The free fall of object does not consider "weight, size and shape" as factors.

technology is the application of the knowledge gained by science.
