Now, I want you to make a prediction in my left hand.

I have a standard size basketball in my right hand, five kilogram medicine ball.

Future simple

If I drop them both at exactly the same time, which one will hit the ground first?

Okay, So which of these objects is being more pulled for the earth?

All right, well, here's what we're gonna do.

I want you to hold both of those above your head.

But gravity is how lighter, how happy something is.

There must be some force that's striking down, and actually actual weight of its main matter has Mass something.

It's always like the white holds it back in a way that doesn't seem so.

I think you might be hitting on an interesting point there.

It's not actually wait that holds it back, but inertia.

That's the tendency of matter to maintain a state of motion so to remain at rest of stationary or to continue with constant velocity when in motion.

One has more mass, so it's got more weight.

But you can clearly feel there's also got more inertia, which means also more sluggish front.

It tends to resist acceleration so that greater force is required to celebrate it.

Is this bone like a heavy car trying to accelerate like a heavy car trying to accelerate?

Well, the force on the medicine ball is greater than the force on the basketball, but it has more inertia and What's really important is that the ratio of forced to inertia is the same for all objects.

So everything accelerates at the same rate and lands at the same time.

Gashes look because it's conducting the heat to the Ice Cube.

Now it's faster than most of us have been captivated by one of these a slinky.

 So why doesn't the space station come crashing into the earth?
