Edexcel iGCSE Physics Equations

Choose the correct equation for Kinetic Energy

• KE = 0.5 x mass x velocity²

• KE = speed x velocty² x mass

• KE = speed x mass / time

• KE = 0.5 x mass / velocity

Choose the correct equation for Gravitational Potential Energy

• GPE = msh

• GPE = mass x speed x height
