Equations

Question 1

Equation for charge flow

Answer 1

Charge flow= current X time

Question 2

Equation for current

Answer 2

Current= charge ➗time

Question 3

Wavelength equation

Answer 3

Wavelength= wave velocity ➗ frequency

Question 4

Frequency equation

Answer 4

Frequency= wave speed ➗ wavelength

Question 5

Equation for acceleration

Answer 5

Change in velocity ➗ time

Question 6

Calculating speed for a graph

Answer 6

Change in distance ➗ time

Question 7

Calculating velocity from a graph

Answer 7

Velocity = change in displacement ➗ time

Question 8

Calculating displacement from graphs

Answer 8

It is the area under a graph so…

1/2 ✖️ base ✖️ height

Question 9

Calculating velocity

Answer 9

Final velocity2- initial velocity2= 2 ✖️ acceleration ✖️ distance

Question 10

Final velocity 2

Answer 10

Final velocity 2 = (2 ✖️acceleration ✖️distance) ➕ (initial velocity)2

Question 11

Calculate kinetic energy

Answer 11

Kinetic energy= 0.5✖️mass✖️(speed)2

Question 12

Calculating speed from kinetic energy

Answer 12

Speed = ✔️(kinetic energy ➗ (0.5 ✖️ mass)
