100
What is an electromagnetic waves composed of?
What is changing electric fields and magnetic fields. (vibrating electric charges)
100
What is air resistance?
What is a friction like force that opposed a motion of objects that move through the air?
100
What is a wave ?
What is a repeating disturbance that transfers energy through matter of space.
200
what are the MAIN three element types found on the periodic table?
What is metal, nonmetal, and metalloids.
200
what is newton's second law of motion and give the formula for it.
What is an object's acceleration is in the same direction as the net force on the object and is equal to the net force exerted on it divided by its mass.
acceleration= net force / mass
200
The human eye detects only a small portion of electromagnetic spectrum called visible light. What are these colors in order?
What is R. O. Y. G. B. I. V.
200
What is a simple machine and give three examples?
What is a machine that does work with only one movement of the machine? Lever, wheel, axel, pulley, inclined plane, wedge and screw.
200
a (blank) is a wave that can only travel thought matter. this wave is also a sound wave.
What is mechanical wave
300
who arranged elements in rows based on increasing atomic mass and in columns based on elements that shared similar physical and chemical properties?
Who is Mendeleev
300
what dose newton's third law state?
What is when one object exerts a force on a second object, the second object exerts a force on the first object that is equal in strength and opposite in direction. (to every action force there is a equal and opposite reaction force)
300
What is the shortest wave on the electromagnetic spectrum?
What is ultraviolet waves.
300
What is the law of conservation of energy?
What is energy cannot be created or destroyed. Energy can only be converted from one form to another or transferred from one place to another.
300
what is a medium and list three.
What is matter through which a wave travels. Gas, solid, and liquid.
400
what is group 1 classified as on the periodic table?
What is alkali metals
400
Define net force
What is the sum of all of the forces acting on an object.
400
What is radio wave? Is it the largest wave on the electromagnetic spectrum?
What is electromagnetic waves with wave lengths longer than 10 centimeters. Yes.
400
What is the equation for mechanical advantage?
What is MA equal output force divided by input force (in newtons)?
400
How do you calculate wave speed?
What is frequency x wavelength
500
What group number are the halogens in and are they all stable?
What is 18 and yes
500
What is Newton's first law of physics and inertia?
What is that an object moves at a constant velocity unless an unbalanced force acts upon it. Inertia is the tendency of an object to resist any change in motion.
500
What does GPS stand for?
What is Global Positioning System.
500
What is a convex mirror?
What is a mirror that curves outward, like the back of a spoon.
500
What is the name of the more dense region of a longitudinal wave and what is the name of the less-dense region?
