Question

The primary factor in decreasing the Kinetic Energy of an object is to:
A. O
Decrease the velocity
Decrease the mass
Decrease the direction
Decrease the stopping distance
D. O

Answer 1

Answer:

Decrease Mass, rather then velocity because the heavier it is the faster it will be

Answer 2

The primary factor in decreasing the Kinetic Energy of an object is to decrease the velocity.

The kinetic energy of an object K = 1/2mv² where m = mass of the object and v = velocity of the object.

Now, for a particular object, its mass remains constant. So, to decrease the kinetic energy of the object, we decrease its velocity since that is the only parameter that can change for the object in question.

So, the primary factor in decreasing the Kinetic Energy of an object is to decrease the velocity.
