General
What is Physics?
Physics is the science of matter and energy.
What is energy?
Energy is the ability to do work.
What is sound?
Sound is vibration.
What is light?
Light is energy we can see.
What is the difference between objects that are transparent, translucent, and opaque? (How do they each interact with light?)
Transparent objects allow all light through. Translucent objects allow some light through. Opaque objects do not allow any light through.
What is matter?
Matter is anything that has mass and takes up space.
What is mechanical energy?
Mechanical energy is movement.
How does sound travel?
Sound travels in waves.
How does light travel?
Light travels in waves.
Give an example for each of the following: transparent, translucent, and opaque.
Answers may vary.
What is force?
A force is anything that causes an object to change speed, direction, or shape.
What is thermal energy?
Thermal energy is heat.
What is amplitude?
Amplitude is a measurement of how strong a sound is.
What is reflection?
Reflection is when light bounces off something.
What are the colors of the visible spectrum, in order?
Who was Sir Isaac Newton?
Sir Isaac Newton was the father of modern physics.
What is potential energy? What is kinetic energy?
Potential energy is energy that is waiting to be used. Kinetic energy is energy that is being used.
What do the three parts of the ear do?
The outer ear collects sound. The middle ear connects the outer ear and the inner ear. The inner turns vibrations in signals the brain understands as sound.
What is refraction?
Refraction is when light bends as it passes through something.
Who discovered that white light can be split into the spectrum?
Sir Isaac Newton discovered that white light can be spilt into the spectrum.
Name at least two of Newton's three laws of motion.
1st: An object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an outside force.
2nd: For an object with a constant mass, force is the product of an object’s mass and its acceleration. (f=m x a)
3rd: For every action there is an equal and opposite reaction.
Name four different types of energy. (Kinetic and potential are categories of energy and do not count for this question.)
Thermal, mechanical, electromagnetic, sonic (sound), radiant (light), gravitational, elastic, nuclear, and chemical.
Who invented the telephone?
Alexander Graham Bell invented the telephone.
What is a lens?
A lens is a transparent object used to bend and focus light.
What is a prism?
A prism is an object used to split white light into the spectrum.
