Question

) Explain, in terms of the forces acting on the ball, why
(i) the acceleration of the ball decreases

Answer 1

$\huge{\mathfrak{\blue{\underline{\underline{\pink{SOLUTION:-}}}}}}$

At the start, the object accelerates downwards due to

the force of gravity. as the object's speed increases, frictional forces such as air resistance or drag increase. at terminal velocity, the weight of the object due to gravity is balanced by the frictional forces, and the resultant force is zero.

Answer 2

Explanation:

The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased.
