physics

Question 1

what is the kinetic energy equation?

Answer 1

kinetic energy = 1/2 x mass x speed^2

Question 2

What is the equation for gpe gravitational potential energy?

Answer 2

Mass x gfs x height

Question 3

What is the equation for power ?

Answer 3

work done / time taken
or
energy transferred / time taken

Question 4

What is the equation for efficiency?

Answer 4

efficiency = useful energy output / total energy input

or

efficiency = useful power output / total power input

Question 5

what is the equation for charge flow?

Answer 5

charge flow = current x time

Question 6

what is the equation for potential difference?

Answer 6

potential difference = current x resistance

Question 7

what is the equation for total resistance?

Answer 7

total resistance = r1 + r2

r1 = resistance of component 1) (r2 = resistance of component 2

Question 8

what is the equation for power ?

Answer 8

power = current x potential difference

Question 9

what is the 2nd equation for power ?

Answer 9

power = (current)^2 x resistance

Question 10

what is the equation for energy transferred ?

Answer 10

energy transferred = power x time

Question 11

what is the other equation for energy transferred?

Answer 11

energy transferred = charge flow x potential difference

Question 12

what is the equation for density ?

Answer 12

density = mass / volume
