Title: How do I calculate Kinetic energy when I know the velocity and momentum? Post by: smmrwds on Dec 17, 2012 I'm doing a physics lab where I have to calculate the kinetic energy in joules. I have the momentum in kgm/s, the velocity in cm/s and the mass in kg to work with.
Title: How do I calculate Kinetic energy when I know the velocity and momentum? Post by: tonigra on Dec 17, 2012 kinetic energy=square of momentum/(2xmass)
from momentum u can find the mass...momentum=mass x velocity and dont forget to change velocity into m/s Title: How do I calculate Kinetic energy when I know the velocity and momentum? Post by: nursing2 on Dec 17, 2012 If you have the mass and velocity both, just plug it into the formula for Kinetic energy
KE=1/2mv^2, If you only have momentum and velocity, use the momentum equation P=mv to calculate mass, and then plug into the KE formula Title: How do I calculate Kinetic energy when I know the velocity and momentum? Post by: illestchemist on Dec 17, 2012 Content hidden
