Jumping off Asteroids in Outer Space & Gravity & Gravitation
Question | Answer |
---|---|
What is Newton's Second Law of Motion? | For an object of certain mass, the greater the force applied to the object, the greater its increase in velocity over time (acceleration) |
What is Newton's Third Law of Motion? | For every action, there is an equal reaction in the opposite direction |
What is acceleration? | An increase in velocity over time. It results from the application of a force to an object |
If something is thrown in a straight line alongside the ground what path does it travel in? | A curved path |
What makes the thing thrown in a straight line travel in a curved path? | Gravity |
Can we see gravity? What do we say it is? | No we can's see gravity -- we call it a force. Because it can't be seen, we can't tell what it is, but rather what it does |
What is Gravitaional Field? | The mass and force that draws them close together. The bigger the mass the stronger the field |
