Physics 1
What type of energy is stored energy that an object possesses due to its position or condition?
Potential energy
What type of energy is associated with the motion of an object?
Kinetic energy
What is the basic structure of an atom?
The nucleus at the center (containing protons and neutrons) and electrons orbiting around the nucleus
What are some factors that influence chemical reactions?
temperature, concentration, and surface area
How many siblings does Miss G have?
One
How do you calculate gravitational potential energy?
formula: GPE = mgh
where:
m represents mass
g represents gravitational field
h represents height
What is red shift?
the shift of light towards longer wavelengths (red end of the spectrum) observed from objects moving away from the observer
What is an element?
A chemical made up of only one kind of atom
What is the atomic number of an element?
the number of protons in an atom's nucleus
Which country is Miss Godinho travelling to over Christmas? (there is two)
Japan & Fiji
What is Newton's first law of motion?
object at rest tends to stay at rest and an object in motion tends to stay in motion with the same velocity unless acted upon by an external force
What is blue shift?
the shift of light towards shorter wavelengths (blue end of the spectrum) observed from objects moving towards the observer
What is a compound?
a substance made from two or more different elements that have been chemically joined
In a chemical equation, what are the reactants and products?
the substances on the left side of the arrow (reactants) and the substances on the right side of the arrow (products)?
Which High School did Miss Godinho go to?
Kings Christian College
What is Newton's second law of motion?
the law that states the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass
(F = ma)
What is the Doppler effect?
the change in frequency or wavelength of a wave for an observer moving relative to the source of the wave
How is the periodic table organized?
the arrangement of elements based on increasing atomic number and grouped into periods (rows) and groups (columns) based on similar properties
What is collision theory?
the theory that states that for a chemical reaction to occur, particles must collide with sufficient energy and proper orientation
What is Miss Godinho's biggest fear?
Stingrays
What is Newton's third law of motion?
the law that states for every action, there is an equal and opposite reaction
What is the law of energy conservation?
the principle that states that energy cannot be created or destroyed, only transferred or transformed
What are the four types of chemical reactions?
1. Synthesis
2. Decomposition
3. Single Replacement
4. Double Replacement
In an endothermic reaction, does the temperature of the surroundings increase or decrease?
Decrease
Where is Miss Godinho's family from?
Portugal/Spain/East Timor
