im not sure can someone please
confirm this for me
The total energy of a system is the sum of: Kinetic Energy Potential Energy Heat All of these.
Part A State the law of conservation of energy The law of conservation of energy states that energy can neither be created or destroyed. Energy can be transferred from one object to another, and it can assume different forms. The law of conservation of energy states that energy can not be created but it can be destroyed. Energy can be transferred from one object to another can be destroyed in a chemical reaction, and it can assumo different forms The...
2. The law of conservation of
energy states: energy cannot be created or destroyed, only
transformed and transferred. Explain how the energy bars visually
show this.

Be sure to answer all parts. Select the correct definition for each of the following terms: (a) law of conservation of energy states that energy can neither be created nor destroyed states that energy cannot be created or destroyed, and cannot change from one form to another states that energy cannot be created or destroyed, but it can be changed from one form to another (b) thermochemistry the study of the conversions among different types of...

In the figure, a 3.9 kg block is accelerated from rest by a compressed spring of spring constant 630 N/m. The block leaves the spring at the spring's relaxed length and travels over a horizontal floor with a coefficient of kinetic friction mu_k = 0.215. The frictional force stops the block in distance D = 7.7 m. What are (a) the increase in the thermal energy of the...
OAL Combine the concepts of conservation of energy and conservation of momentum in inelastic collisions. In figure a, a bullet and a wooden block are shown in two configurations. In the first configuration, the block, labeled m2, hangs vertically from a ceiling. A bullet, labeled m1, approaches the block horizontally from the left. A rightward arrow points from the bullet and is labeled vector v1i. A rightward arrow, shorter than the first, points from the block and is labeled vector...
