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 fo...
Newton's Laws
28 Sep 2021
Contributed by Lukas
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 ...
Projectile Motion - Part 2
20 Sep 2021
Contributed by Lukas
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 k...
Projectile Motion - Part 1
18 Aug 2021
Contributed by Lukas
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 ...
What Goes Up Must Come Down
05 Aug 2021
Contributed by Lukas
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 vertic...
Launching Upward
29 Jul 2021
Contributed by Lukas
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, ...
The Kinematic Formulas
22 Jul 2021
Contributed by Lukas
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 ti...
Free Fall
14 Jul 2021
Contributed by Lukas
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 motionBe...
Graphing Position, Velocity & Acceleration
07 Jul 2021
Contributed by Lukas
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 ...
Acceleration
30 Jun 2021
Contributed by Lukas
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 quickl...
Speed vs Velocity
16 Jun 2021
Contributed by Lukas
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...
Scalars vs Vectors

Contributed by Lukas
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....
Distance vs Displacement
02 Jun 2021
Contributed by Lukas
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 goi...
