you can break newton's law into two cases. the first would be "an object at rest stays at rest unless acted on by an external force". that sounds like it would be really easy to believe if you were a renaissance person. the second case is "an object in motion will stay in motion unless acted on by an external force". why do you think this would be harder to understand if you were a renaissance peasant?

Which of the following is newtons first law of motion

Energy can neither be created or destroyed

an object in motion stays in motion until acted on by an unbalanced force

Entropy is always increasing

force= mass x acceleration

you can never achieve absolute 0

For every action there is an equal and opposite reaction

The rate or speed an object moves in a given direction

The change in rate or speed an object moves in a given direction

match

you'll notice that they didn't say there was no gravity, just that it was a microgravity environment. but when the space station isn't reboosting, that they couldn't feel any gravity. What happened when he set the camera to float when the space station was NOT reboosting?

it drifted towards the camera

it was entirely stationary

it moved around a little because of air moving, but not a lot

it fell towards the ground

when the reboost happened, did you see anything physically push the camera?

yes

no

but the camera moved, even though a force wasn't acting on it. this is because

the force was on the ship, and everything inside the ship moved

the camera stayed at rest in its part in space, but the spaceship moved around it.

the camera is attached to the ship, so the force is only on the camera

vocab word - inertia is the tendency of an object to resist change. this means that

Things with a lot of inertia are easier to move than less inertia

things with a lot of inertia are harder to move than less inertia

things will move at the same rate from the same force no matter what their inertia is

The string pulled back the same amount gave the same amount of force for each object.

high mass object		fast acceleration
low mass object		medium acceleration
medium mass object		slow acceleration

When moving in a straight line, inertia is just another word for mass

ok

but they mean different things, right?

wait, if they don't mean different things, why did you make a new vocab word for it?

A train is moving towards you at 20 mph. your kid sister jumps in front of the train to stop it. does your reaction to this sentence change if you know the train is a toy train that is less than 2 kg in mass?

yes, a toy train and a real train are very different scenarios

no, to stop the train, you have to slow either train down from 20 mph to 0 mph, that is bad.

8th grade and Honors section: explain why old fashion cannons always had wheels on them (it wasn't just for moving them into position)

Its math time! the cannon weighs 1,500 kg and can shoot a cannonball that weighs 15kg. compare the acceleration of both the cannon and the cannonball

the cannon is 100 times heavier, so its acceleration will be 1/100th times the acceleration of the cannonball

the cannon is 100 times heavier, so it will accellerate 100 time more than the cannonball

the cannon and the cannonball will move away from each other each going to the same speed in opposite directions
