1. The speed formula: Speed= Distance / time
2.Distance traveled = Area under graph
Area of triangle A + Triangle B + Triangle C
3.Remember formula a= v-u/t
4. A resistor and a power supply are two things which affect the current size.
5.
6. Potential difference is Initial Voltage - Current voltage.

8. The number of waves per second is the FREQUENCY
The time Taken for each was is it's PERIOD
9.Law of reflection is angle of incidence = angle of reflection
10. Diffraction:
