In successive an object moves from start position, then moves 1ft, 4ft and 8ft. This is an example of a. non-uniform motion b. uniform acceleration c. uniform motion d. free fail in Earth's gravitational field.

Answer:Non-uniform motion

Explanation:

This is an example of Non-uniform motion because unequal distance traveled by an object in equal interval of time is termed as Non-Uniform motion and here also the distance traveled by object is 1 ft, 4 ft and 8 ft which is different from each other.

In Uniform motion distance traveled is equal in equal interval of time.
