Newton's third law of motion | arrow_right_alt | An object in motion stays in motion, an object at rest stays at rest until acted on by an outside force |
Newton's first law of motion | arrow_right_alt | force = mass x acceleration |
Newton's second law of motion | arrow_right_alt | for every action there is an equal and opposite reaction |
Watch the following video on newton's first law of motion. Any questions?
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?
when the reboost happened, did you see anything physically push the camera?
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
The string pulled back the same amount gave the same amount of force for each object.
| Draggable item | arrow_right_alt | Corresponding Item |
|---|---|---|
high mass object | arrow_right_alt | fast acceleration |
low mass object | arrow_right_alt | medium acceleration |
medium mass object | arrow_right_alt | 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.

Pushing off the wall at the ice skating rink and going the opposite direction is an example of Newton’s
A cart accelerating slower when mass was increased is an example of Newton’s
A _______________________ is a push or a pull on an object.
A driver without a seat belt getting thrown from the car in a collision is an example of Newton’s
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
