Problem Solving in Physics

Conservation of Energy

Energy is usually conserved. Carefully note what kinds of energy you start and finish with and make them equal to each other.

Conservation of Momentum

Are there any eternal forces?


No, Great! Momentum is conserved, so final momentum=initial momentum!

Are there any eternal torques?

No, Great! Angular momentum is conserved! Initial=final.



Check your formula sheet - are there any formulas that have the variables you need to solve this problem?

Trig Identities

Solving a triangle? Use SOH CAH TOA to find unknown quantities

Sum of the Forces

Remember, the Sum of the Forces F=ma - if there is no acceleration, there is no net force!

This works for the sum of the torques too. The sum of the torques =I(alpha)
