Physics Formulas

Question 1

What is the equation used for Kinetic Energy?

Answer 1

Kinetic Energy = 0.5 x mass x velocity squared

Question 2

What is the equation used to find gravitational potential energy?

Answer 2

GPE = m x g x h
Mass, Gravity and Height are on the bottom and Gravitational Potential Energy is on the top.

Question 3

What is the equation used for Work Done?

Answer 3

W = F x D W (Work Done) F (Force) D(Distance)
F and D are on the bottom and W is on top

Question 4

What is the equation for Ohm’s Law?

Answer 4

V = I R I (current) R (resistance) V(Potential Difference)
I and R on the bottom and V on the top

Question 5

what is the equation for potential difference?

Answer 5

V = E Q V (Potential Difference) Q (Charge) E (Energy)
V and Q are on the bottom and E is on top

Question 6

what is the equation for current?

Answer 6

I = Q T I (current) Q (charge) T (time)
I and T on the bottom and Q on the top

Question 7

What is Neutron Emission equation?

Answer 7

The “n” (neutron) stays the same:
The atomic mass decreases by 1
The atomic number is unchanged

Question 8

Why is the atomic mass and number unchanged in Gamma Equation?

Answer 8

There is no change to make up of the nucleus and so a new element is NOT formed

Question 9

What is a Beta Decays Equation?

Answer 9

The “e”(electron) stays the same:
Mass Number is unchanged
Atomic Number increases by 1

Question 10

What is an Alpha Decays Equation?

Answer 10

The helium stays the same and the:
Mass Number decreases by 4
Atomic Number decreases by 2
