Acceleration

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 about the acceleration.

They are talking about how quickly their car's velocity can change from 0 mph to 60 mph.

Objects don’t just stay at a constant velocity, always moving at 2 m/s. They speed up and slow down. That change from 2 m/s to 10 m/s as an object speeds up or from 2 m/s to 1 m/s as the object slows down, is the acceleration.

We can make a connection here.

We talked about velocity as change in position over time.

Acceleration is the change in velocity over time.

Forces

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 to...

Newton's Laws

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 ma...

Projectile Motion - Part 2

Projectile Motion - Part 2

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 launch...

What Goes Up Must Come Down

What Goes Up Must Come Down

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 downWe started off by thinking about ...

Launching Upward

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 other...

The Kinematic Formulas

The Kinematic Formulas

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 they...
