Energy
As a roller coaster goes up and down hills, this happens to the amount of mechanical energy.
What is stays the same?
A hair dryer changes electrical energy into this.
What is thermal energy?
A wave having a long wavelength would have this type of frequency.
What is low?
This law of motion is evidence when a coin falls in a cup when the card is moved.
What is Newton's First Law?
This item is a magnet moving inside a coil of wire to produce electricty.
What is an electromagnet?
This is a way to increase the potential energy of an object.
What is raise the height of the object?
Swinging a hammer is an example of this type of energy.
What is mechanical?
Sound waves require this to pass through.
What is a medium?
A straight line on a speed time graph indicates the person is doing this.
What is stopping?
This is true when a magnet is cut in half.
What is each new magnet will have a north and south pole?
This is true of colder particles of matter.
What is they have less energy?
This type of energy is stored in foods we eat?
What is chemical energy?
A disturbance that transfers energy.
This causes a ball to accelerate in a downward direction after it is thrown.
What is gravity?
The movement of electrically charged particles.
What is electric current?
This says that energy cannot be created or destroyed.
What is the law of conservation of energy?
In a pot of boiling water, the hotter water will be at the bottom due to this energy transfer.
What is convection?
This type of wave is made when each part of the wave moves up and down as the wave moves across.
What is a transverse wave?
According to Newton's 3rd law, this is true of two colliding objects.
What is each objects exerts an equal and opposite force on other?
To become electrically charged, an object loses this.
What is electrons?
This happens when two objects of differing temperature come in contact with each other.
What is the heat moves hot to cold objects?
Energy that is lost in energy transformations becomes this.
What is waste energy?
This color of light is reflected when viewing a yellow banana.
What is yellow?
A car is traveling 2 kilometers at a speed of 45 kph. This additional information is needed to determine velocity.
What is direction?
This determines whether an object is magnetic or not.
