SECTION 2003
The combining of one substance with another to yield a different product is the result of a(n):

Kinetic energy = 1/2mv^2. since the mass is constant we can form a ratio of it's kinetic energy at 60 divided by that at 30 to see ke(60)/ke(30) = +(60^2)/30^2). this may be said to 300% increase.

The objects are acted upon by only one force. gravity. mass times the acceleration of gravity (-9.81meters/second squared).

Answer mechanical energy;
