Waves
What type of wave is a microwave?
Electromagnetic
What force pulls objects towards Earth?
Gravity
Momentum is the product of mass and this
Acceleration
If a balanced atom loses an electron, what is its new charge?
Positive
This type of bond involves one element giving it's valence electrons to another element, resulting in both now having full outer energy shells
Ionic Bond
What type of wave is a soundwave?
Mechanical
If there are 10N of force pushing an object left and 20N of force pushing an object right, which direction will the object move?
What is the net force of a semi truck that weighs 80,000kg's travelling 2kph when it collides with a stationary object?
160,000N
How many valence electrons are in the first energy shell?
2
This type of bond involves two elements sharing valence electrons in their outermost energy shell.
Covalent Bond
Frequency measures what in a wave?
The number of wave cycles in a second
What is Newton's 1st Law?
The Law of Inertia. An object at rest will stay at rest and object in motion will stay in motion unless acted upon by an outside force.
If two cars weigh exactly the same, what determines which car will provide more force in a collision?
If the acceleration of one car is higher, that car will collide with more force
When an atom has a charge, it is called what?
An Ion
This element has the largest atomic radius
Francium
What is a medium in terms of a wave?
The material that a wave travels through
What is Newton's 2nd Law?
The acceleration of an object depends on the net force acting upon it.
Motion related energy is called what?
Kinetic Energy
How many valence electrons do the Halogens have?
7
It increases
What does a wave carry from one place to another?
Energy
What is Newton's 3rd Law?
For every action there is an equal and opposite reaction.
Energy due to position or condition is called what?
Potential Energy
What happens to atomic radius across a period?
It gets smaller
This type of electromagnetic wave creates ions in the body as ionizing radiation
X-Ray
