To help you remember the formulas for kinetic and potential energy, here’s a simple guide:

1. Kinetic Energy (KE):

   • Formula: KE = 1/2 mv²
   • Easy Reminder: "Half the mass times the speed squared."
   • Example: If you have a 2 kg object moving at 3 m/s:
     KE = 1/2 × 2 × 3² = 9 Joules.

2. Potential Energy (PE):

   • Formula: PE = mgh
   • Easy Reminder: "Mass times gravity times height."
   • Gravity Value: g is about 9.81 m/s².
   • Example: If you have a 2 kg weight that is 5 m high:
     PE = 2 × 9.81 × 5 = 98.1 Joules.

These formulas help us understand how energy works in moving objects and items held up high!
