Question

The kinetic energy of a body falling downward :
a. remains constant
c. increases
b. decreases
d. first decreases then increases

Plz tell me quickly​

Answer 1

Answer:

Hey! This is your answer

Explanation:

When the object is dropped, thrown downward or projected upward, its kinetic energy becomes KE = mv2/2, along with a factor of the initial velocity. The sum of the PE and KE is the total energy (TE), which is a constant.

Answer 2

As an object falls from rest, its gravitational potential energy is converted to kinetic energy. Conservation of energy as a tool permits the calculation of the velocity just before it hits the surface. K.E. = J, which is of course equal to its initial potential energy.
