Physics 2 core practicals Flashcards
1
Q
What is the equations for voltage
How do you investigate for resistance
A
Voltage = current x resistance
Current should increase proportionally
Construct circuit
Record the current and potential difference calculate resistance , keep changing wire
2
Q
How to investigate density
A
Determine the volume for irregular shapes
Find the mass using a scale
Use a displacement method
Fill a eureka can wil water
Place object in the water Meaisre the volume of water that has been displaced into the tube
3
Q
Investigate water
A
Use a ripple tank
I’m the tank is vibrating bar which is attached to power pack
Paper underneath
When light shines an image of waves is seen on the paper
Use this to measure wavelength , speed
Wave speed = frequency Wavelength
