In mathematical physics, equations of motion are equations that describe the behaviour of a physical system in terms of its motion as a function of time.

This may make defining the vectors simpler when writing the equations of motion.

If these parametric equations really are describing some type of motion, it would be counterclockwise.

Adding equations (1) and (2) results in an equation describing the center of mass (barycenter) motion.

And I encourage you to watch the kinematics videos, the projectile motion videos, if you want to know where the equations come from.

have some number of equations, say n equations and n unknowns.

That's true with regular equations or differential equations.

Systems of linear equations.

I was able to reduce this system of equations to this system of equations.

both equations.

Exact equations.

Separable equations.

So both of these parametric equations, both sets of parametric equations have the exact same path.

And this first class of differential equations I'll introduce you to, they're called separable equations.

Newton's three laws of motion the first law of motion says that objects in motion stay in motion forever unless acted upon by an outside force.

Math, differential equations.

Two linear equations of to unknowns.

Newton's laws of motion an object in motion stays in motion, unless it's affected by a net force.

The equations in contexts outside of general relativity are still referred to as the Einstein field equations.

We'll now move from the world of first order differential equations to the world of second order differential equations.

Is the system of linear equations below dependent or independent, and they gave us two equations right here.

Solve the system of equations by graphing.

Solve the system of equations by substitution.

Let's do some examples of solving equations.

Let's solve this set of linear equations.

Let's just solve this system of equations.

So the differential equations.

And when you study exact equations in differential equations, you'll see this a lot more.

Anyway, hopefully that these examples made you a little bit more comfortable with graphing equations and reading graphs of equations.

And I just used both of these equations.

We could go to either of these equations.
