Conservation of mechanical energy is defined as (a) Energy of motion

(b) Law of conservation of energy

(c) The sum of the kinetic and potential energies of an object remain a constant value unless there are forces acting on the object that cause a loss of energy overall, such a friction and air resistance.

(d) Potential energy added to kinetic energy

Janel’s class studied properties of matter and how matter can change. janel decided she would do an experiment mixing baking soda and vinegar. question: describe the properties of baking soda and vinegar, and explain the changes that janel should see when she mixes the two types of matter. •first, identify the physical state of matter of baking soda. describe another property of baking soda. •next, identify the physical state of matter of vinegar. describe another property of vinegar. •then, explain what janel should see when she mixes the baking soda and vinegar. •describe the states of matter of the new materials that are formed. •explain how janel can be certain a change has occurred. me
