Physics equations

Question 1

kinetic energy equation

Answer 1

kinetic energy(j)= 1/2 × mass(kg) × speed squared(m/s)
E= 1/2mv squared

Question 2

change in energy equation

Answer 2

energy change= mass × gravitational field strength (N/kg) × height (m)
E= mgh

Question 3

Elastic potential energy equation

Answer 3

Elastic potential energy= 1/2 × spring constant × extension squared
E= 1/2ke squared
