Kinetic Energy Equation: Calculating Mass and Speed | GCSE Physics (9-1) | kayscience.com

In this video you will learn all the science for this topic to get a grade 9 or A* in your science exams!



The formula for an object’s kinetic energy is:
kinetic energy = 0.5 x mass x speed2
The unit for kinetic energy is joules ( J )
The unit for mass is kilograms ( kg )
The unit for height is metres ( m )
To rearrange the formula for mass: m = Ek ÷ ( 0.5 x v2 )
To rearrange the formula for height: V= √("Ek" /( 𝟎.𝟓 𝒙 𝒎))
