These collisions are the easiest to analyze, and they illustrate many of the physical principles involved in collisions. The conservation of momentum principle is very useful here, and it can be used whenever the net external force on a system is zero. We start with the elastic collision of two objects moving along the same linea one-dimensional problem. An elastic collision is one that also conserves internal kinetic energy. Internal kinetic energy is the sum of the kinetic energies of the objects in the system. Figure 8.6 illustrates an elastic collision in which internal kinetic energy and momentum are conserved. Truly elastic collisions can only be achieved with subatomic particles, such as electrons striking nuclei. Macroscopic collisions can be very nearly, but not quite, elasticsome kinetic energy is always converted into other forms of energy such as heat transfer due to friction and sound. One macroscopic collision that is nearly elastic is that of two steel blocks on ice. Another nearly elastic collision is that between two carts with spring bumpers on an air track. Icy surfaces and air tracks are nearly frictionless, more readily allowing nearly elastic collisions on them. Elastic Collision An elastic collision is one that conserves internal kinetic energy. Internal Kinetic Energy Internal kinetic energy is the sum of the kinetic energies of the objects in the system. Q: An elastic collision is one that conserves internal energy of what type? A:
A:
output: kinetic

Answer the following question given this paragraph: Q: What's the name for the process where pollen is transferred to the ovules of a seed plant? A:

OPTIONS:
- combination
- condensation
- hibernation
- pollination

Answer: pollination

Problem: OPTIONS:
- parthenogenesis
- synthesis
- evolution
- metamorphosis
Q: Answer the following question given this paragraph: After hatching, most arthropods go through one or more larval stages before reaching adulthood. The larvae may look very different from the adults. They change into the adult form in a process called metamorphosis. During metamorphosis, the arthropod is called a pupa. It may or may not spend this stage inside a special container called a cocoon. A familiar example of arthropod metamorphosis is the transformation of a caterpillar (larva) into a butterfly (adult) (see Figure below ). Distinctive life stages and metamorphosis are highly adaptive. They allow functions to be divided among different life stages. Each life stage can evolve adaptations to suit it for its specific functions without affecting the adaptations of the other stages. Q: What is the process of larva becoming an adult called? A:
Answer: metamorphosis

Problem:OPTIONS:
- eels
- coral
- sharks
- mollusks

Answer the following question given this paragraph: Mollusks reproduce sexually. Most species have separate male and female sexes. Gametes are released into the mantle cavity. Fertilization may be internal or external, depending on the species. Fertilized eggs develop into larvae. There may be one or more larval stages. Each one is different from the adult stage. Mollusks (and annelids) have a unique larval form called a trochophore. It is a tiny organism with cilia for swimming. Q: The trochophre, a unique larval form, is found in the life cycle of which animal classification. A:
****
A: mollusks

Answer the following question given this paragraph: One useful application of PET scanning is in the diagnosis of Alzheimer's disease. This debilitating condition associated with memory loss primarily occurs in elderly individuals. A protein known as beta-amyloid gradually forms deposits, or plaques, in the brain. Severe memory loss and impaired movement appear to be direct results of the plaque growth. Q: Alzheimers disease is associated with memory loss in what group of people? A:
OPTIONS:
- juveniles
- prehistoric
- immigrants
- elderly
elderly

OPTIONS:
- the spinal cord
- the backbone
- the vessels
- the cell

Answer:
the cell
