Motion can be understood as changing this, also known as an object's location.
What is position
Energy can be defined as the ability to cause change or do this.
What is work
When mechanical energy is used to create a force that moves an object, it is called this.
What is work
What is total
The substance that a mechanical wave travels through is called this.
What is its medium.
Measuring a how far an object changes its position in one specific direction gives us this property measured in meters.
What is displacement
This type of energy comes from the movement of particles like atoms and molecules that make up objects.
What is thermal energy.
Calculating the amount of work done on an object requires you to know the amount of force used and this other variable.
What is distance
Thermal energy is transferred when there is a difference in this property between objects.
What is temperature
Measuring between these two points will give you the amplitude of a wave.
What is the resting position and a crest (or trough).
This property is always positive and describes how far an object moves per unit of time regardless of the direction.
What is speed
When an escalator carries people up to another floor, it is an example of converting electrical energy to this type which includes kinetic and potential energy.
What is mechanical energy
This is an object that changes force to make work easier despite have few or no moving parts.
What is a simple machine
Convection is a transfer of thermal energy in fluids because of differences in this property that is related to differences in temperature.
What is density
This term describes the bending of a wave because it enters a new medium at an angle and slows down.
What is refraction
If an object has a constant velocity, it means this property, which measures how fast velocity changes, must be 0.
What is acceleration
A log placed on a fire will help it keep providing light and warmth. The energy for the light and warmth comes from a reaction transforming this type of potential energy stored in the molecules of the wood.
What is chemical potential energy
A simple machine can decrease the force needed, it can decrease the distance needed, but it can never decrease this.
An object with a small value for this property will change temperature very easily because it does not require much energy.
What is specific heat
This is calculated by multiplying a wave's frequency by its wavelength and determined by the medium it travels through.
What is wave speed.
The negative slope section on this graph tells us this about the object's motion relative to its starting point.
What is it's moving back toward starting point
To increases thermal energy in a substance, you can increase either of these 2 properties. (must name both)
What are temperature and mass
Either of the 2 ways to calculate the mechanical advantage of a simple machine.
What is Fout/Fin or Din/Dout
Out of the following: thermal energy, temperature, and specific heat- it's the one(s) that would change if you add or take away mass.
What is thermal energy
The Doppler Effect refers to an apparent change in this wave property when the source of a wave and the receiver are moving relative to each other.
What is the frequency
