Instantaneous is at one moment in time and average is over a period of time.
What is the formula for force.
Explain the difference between potential and kinetic energy
Kinetic is in motion and potential is stored.
The transfer of thermal energy is always from
What is the top of the wave called
crest
What is an insulator
stops/slows current
Formula for speed
S=D/T
What is the difference between an balanced force and a unbalanced force.
Which of the following has kinetic energy?
1. water flowing down a river
2. a bowling ball rolling down an alley
3. atoms inside a rock which is sitting on a cliff.
all
Convection currents.
There are some waves that are close together in one system and some waves that are further apart in another. what is changing?
Frequency is decreasing and wavelength is increasing
as mass increases force also increases.
Explain at what point on a rollercoaster does the cart have the most potential energy
The top of the first hill.
The sun is what type of thermal energy
Radiation
What is the difference between longitudinal and transverse wave.
slinky and wave.
An open circuit means
does not allow electricity to flow.
Which is not accelerating?
A. taking a curve at a constant speed
B. moving at a constant speed
A
5 m/s2
When it is compressed.
Conduction
What is destructive interference
they cancel out
when a piece of glass is inserted into a simple circuit, the light bulb of the circuit does not light up. Under these conditions this would mean the glass is a
insulator
A bus traveling at 50 km/hr for 3.8 hours. The distances traveled will be-
190 km
The car will have a greater acceleration than the bus.
The mechanical energy of a system is equal to the kinetic energy plus the potential energy within the system. Explain why the total mechanical energy of a system remains constant in a frictionless environment.
Due to the law of conservation, energy cannot be created nor destroyed. Energy will only change forms.
a student is using a simple circuit of wires, a battery, and a small light bulb to test objects for electrical conductivity. How would the students know which object is the best conductor
the light got brighter.
