# Kinematics vs. Dynamics

Some of the main types of problems you will encounter in your beginning physics classes are dynamics and kinematics problems. Below you will see how these types of problems are the same and how they are different.

*Remember: the best way to solve any problem in physics is with a picture

## Kinematics

Kinematics tells us how something is moving

We use kinematics to solve dynamics questions

Usually, kinematics will involve your position/velocity/acceleration information

Ask:

How are these pieces of information related?

How are these pieces of information different?

How can I use what I have to connect pieces of information?

## Dynamics

Dynamics tells us what forces are at play

When solving a dynamics problem, always draw a free-body diagram (FBD)

We need to first figure out how this object is going to move

After we figure out how it is going to move, then it becomes a kinematics problem
