Name That Energy
The ability to cause motion or create change
Energy
Kinetic and potential energy have noting to do with mechanical energy?
False, mechanical energy is the energy an object has depending on its position or motion.
Explain Translucent, Transparent, and Opaque objects
Translucent: allows some light to pass through
Transparent: allows all light to go through
Opaque: does not allow light to pass through
Friction
When two objects rub against each other. This makes things slow down and heat up.
The flow of heat
Thermal energy
The Law of Conservation states energy cannot be created or destroyed, only transferred.
True
Conduction, convection, and radiation have to do with...
allowing heat to flow.
Force
A push or pull
Charged particles that are moving around
Electricity
Conductors like copper and water allow electricity to flow through them
True
Explain Mechanical waves
Sound travels in waves called mechanical waves
Newtons 1st Law of Motion
An object at rest stays at rest and in object in motion stay in motion until a forces acts on it.
A bowling ball rolling down the lane is
Kinetic energy
Light Travels in a straight line and never stops.
False, light travels in a straight line until it hits something.
the speed of waves are referred to...
Frequency
Newton's 2nd Law of Motion
The greater the mass of an object, the more force you need to accelerate the object
A boulder at the top of mountain
Potential Energy
The rubbing coating around conductors are called Insulin and they allow electricity to flow through them
False, they are called Insulators and do not allow electricity to flow through them.
Why can't we hear in outer space?!
Sound travels through matter and there is no matter in outer space. Outer space is silent.
Acceleration
the change in speed
