So what is a force?

A force is really just a push or a pull on an object. It occurs when two objects interact with each other. Forces can be contact forces, meaning that the objects have to actually t…

Let’s forget the math today and focus on Newton’s Laws.

Newton was a mathematician and physicist born in the 1600s. He existed, taught and studied well before many of our modern discoveries had been m…

However, we don’t always just move objects at a parallel to the ground. More often than not, we move them at an angle. Think about your field goal kickers on a football field or a missile being launc…

I promised an exciting episode that would take us into a whole new dimension.

Let’s start talking projectile motion → the movement of objects that break beyond just one dimension and instead travel bo…

The past few weeks we have moved on from talking about objects moving horizontally, back and forth, and started to talk about objects that move vertically, up and down

We started off by thinking about…

An important thing to keep in mind as we discuss upward vertical motion → we are talking about objects launching straight up into the air. Ideally, without wind or disproportionate weight or any othe…

Last week we listened to the start of a new idea. We expanded on motion and are now talking about up and down → vertical motion.

We spent a lot of time getting accustomed to objects moving - where the…

We are going to spend the next episodes talking about TWO dimensional motion. UP & left, down & right. We are adding a whole new dimension to motion

Before we do that,

We are going to check off one mor…

We are wrapping up one dimensional motion today with all of the key ideas covered. We’ve talked about distance and displacement, speed and velocity and last week we talked about acceleration as the r…

Let’s get to it.

Acceleration is the rate of change of an object's velocity. It is how the velocity changes. When car companies brag about how quickly their vehicles go from 0 to 60, they are talking …

How do we discuss HOW FAST an object moves?

Let’s start with speed:

SPEED is the rate at which an object covers ground.

If you’re a math head like me:

SPEED is distance divided by time , the distance an …

If you didnt listen to my last episode on Distance vs Displacement - give that one a listen for a little bit of context on how we talk about movement.

In the last episode we determined that there are…

Let's start off by discussing the idea of movement.

What is movement?

How can someone move?

Do we care about direction?

Do we care how fast someone is going?

If we really want to start off with the basics…
