Energy & Momentum Homework: How Are They Related?

[physics_geek]

Homework Statement

just a very basic question...how is energy related to momentum

Homework Equations

The Attempt at a Solution

im not sure but i think the answer is that they both have something to do with work..can someone help clarify..thanks

umm hello..anyone?

 

[physics_geek]

does like nobody no the answer?

What is the formula for momentum, and what is the formula for kinetic energy?

hi

Momentum = mv (mass x velocity)

Potential energy = mg∆h (mass x acceleration due to gravity x ∆ height)
Kinetic energy = 1/2 mv^2 ( 1/2 x mass x velocity squared)

work done = force x distance traveled in the direction of the force

since work done is energy

it follows that energy = force x distance

maybe you can derive a relationship from the information above

hope that helped

I am adding on that you may want to consider the Impulse-Momentum Theorum (it should make it easier to deal with force)
