Which factor can increase both potential energy and kinetic energy of an object?

a. increase in speed
b. increase in mass
c. decrease in temperature
d. decrease in height from the ground.

B:Increase in Mass.

Explanation:

We are given that potential energy and kinetic energy of an object  

We have to find that which factor can increase both potential energy and kinetic energy of an object.

We know that potential energy of an object=mgh

Kinetic energy of an object=

Where m=Mass of an object

v=Velocity of an object

g=acceleration due to gravity

h=Height of an object from the ground

Kinetic energy depends on mass and velocity of an object.

While potential energy depends upon mass and height of an object and acceleration due to gravity.

When we increase in mass then kinetic energy and potential energy of an object also increases.

Hence, option B is true.

B:Increase in Mass.
