What equipment do you need for the spring investigation experiment?
Spring
Weighted stand
ruler
a boss
stopwatch
What is the independent variable in the spring investigation?
(a)
What is the dependent variable in the spring investigation?
(a)
How would you improve the accuracy of results?
Add a marker to the bottom of the spring
Repeat 3 times and calculate a mean
Use a millimetre ruler
Use a weighted stand
What is the relationship between force and extension?
(a)
Plotted on a graph, what is the area under the force-extension graph equal to?
(a)
What equipment is needed in the investigation of mass and force's affect on acceleration?
A ruler
A trolley
A light gate
Masses
A piece of string
What is the use of the piece of card in the mass, force and acceleration investigation?
Gives the trolley more mass
Interrupts the signal of the data logger so a velocity can be calculated
Interrupts the signal so the data logger can calculate acceleration
Interrupts the signal so the data logger can calculate force
Makes it look nicer
What do we need to know the mass of in order to get the right results?
(a)
What are the control variables to the force, mass and acceleration investigation?
The distance between the starting line and the light gate
Surface of the track
Mass of hook and trolley
Mass of entire system
Length of piece of card
When investigating the effect of mass, where do you add the masses?
(a)
Where do add the masses to investigate force?
(a)
What is the equipment for the wave speed on water experiment?
Signal generator
Ruler
Stopwatch
Strobe light
String
What piece of equipment do we increase the frequency of until the wave pattern freezes?
(a)
How do we work out the wavelength?
Calculate wave speed and divide by frequency
Measure the distance between each wave
Measure the distance between 10 shadow lines and divide by 10
Read of the signal generator
What equation is needed to work out wave speed?
Wave speed= wavelength x frequency
Wave speed= distance/time
wave speed= frequency/wavelength
Wave speed= 1/Frequency
What equipment is needed for the wave investigation on strings?
Strobe light
Vibration Transducer
Signal generator
Masses
Ruler
What do we use to change the length of the wave created on the string?
(a)
When does the string get measured?
Just before the string snaps
When the timer goes off
When the frequency of the signal generator is equal to mass
A clear wave appears of the string
What equipment is needed in the investigating reflection experiment?
Ray box
Ruler
Pen/pencil
Protractor
Mont Blanc
The angle of reflection is always equal to...
(a)
What is used to investigate emission?
(a)
What do you fill the Leslie Cube with?
(a)
To measure emission at each side, hold an ______ ________ 10 cm away from each side
(a)
Name a control variable about the infrared detector
Same brand
Same environmental conditions
Fixed distance
Same age
Name the equipment for the melting wax investigation?
Wax
Different metal plates
Thermometer
Bunsen Burner
Different surfaces of plates
In the melting wax experiment how can you tell which is the better absorber and emitter of energy?
(a)
