Question

5. Give scientific reasons.
a. When an object falls freely to the
ground, its acceleration is uniform.
b. Even though the magnitudes of
action force and reaction force are
equal and
their directions are
opposite, their effects do not get
cancelled.
d​

Answer 1

Answer:

a)When an objects falls freely its acceleration is constant because in a free fall the acceleration does not depends on the mass of body . the uniform acceleration is produced due to gravitational force as long as air resistance can be ignored and the object stays near enough to the earth's surface so that the gravitational field is constant.
