Draggable item		Corresponding Item
Newton's second law of motion		An object in motion stays in motion, an object at rest stays at rest until acted on by an outside force
Newton's third law of motion		force = mass x acceleration
Newton's first law of motion		for every action there is an equal and opposite reaction

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?

Required

1

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

Required

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

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?

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

1

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

Draggable item		Corresponding Item
low mass object		fast acceleration
medium mass object		medium acceleration
high mass object		slow acceleration

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

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?

Explain the last question in terms of Newton's second law.

A cart accelerating slower when mass was increased is an example of Newton’s

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
