Vocabulary
System
A set of interacting parts (2 or more)that forms a complex whole / performs a function
What do the magnetic field lines look like when magnets repel?
The field lines go from one pole to the other pole of the SAME magnet- from N to S and vice versa.
A spaceship is traveling through space. Suddenly, its speed increases. What can you say about the relationship between kinetic energy and speed of the spaceship?
The kinetic energy increases as the speed increases
What is inertia?
An object in motion wants to stay in motion. an object at rest will stay at rest.
Which many bones does an adult human have?
Electromagnet
A type of magnet in which the magnetic field is produced by an electric current
What are 3 ways an electromagnet is different from permanent magnets?
- It can be turned on and off
- Poles can be reversed
- The strength can be adjusted
Two repelling magnets are 8cm from each other. What can you do to increase the potential energy stored in the system?
Hold the magnets so that they are as close as possible to one another
What is the difference between phenotype and genotype?
how many US states touch the water?
23
What represents the strength and direction of the magnetic field
Magnetic fields lines
What happens to the potential energy of attracting magnets when they are moved apart.
What happens to the energy in a system of magnets when the magnetic force causes two magnets to move?
The potential energy gets converted to kinetic energy. The more potential energy there is, the more energy there will be available to convert to kinetic energy.
How does the digestive system & the nervous system work together to help the body function?
When the stomach is full, the mechanical receptors in the stomach send signals to the brain. Vice versa with hunger.
Who painted the Mona Lisa?
Leonardo Da Vinci
Energy
The ability to make things move or change
How does the law of conservation of energy relate to magnetic fields?
Potential energy is stored in the magnetic field when magnets are moved against the magnetic force. Once it is let go, it converts to kinetic energy
What happens to the amount of potential energy in repelling magnets when you move the magnets closer together?
In repelling magnets (same side poles), the amount of potential energy will increase when you move the magnets closer together.
Widows peak (B) is dominant to a regular hairline (b). A person with a widows peak (Bb) has a baby with someone with the (bb) allele. What is the likelihood that they will have a baby with a straight hairline?
50%
Who has the world record for the most Olympic gold medals?
Michael Phelps
Magnetic Field
The space around a magnet in which magnetic forces can act on objects
Where is the force of attraction the strongest on a magnet?
At the poles
What is responsible for Earth's magnetic field?
Its liquid iron core
What are the nitrogen base pairs in DNA?
ATGC
What year did the first iPhone come out?
2007
