Question | Answer |
energy stored in chemical bonds between atoms | chemical energy |
energy of hot objects | thermal energy |
energy of opposition potential | potential energy |
energy of motion | kinetic energy |
In what direction does an object accelerate? | in the direction of the force |
How does friction affect moving objects? | slows it down |
mass x acceleration: work examples from your notes | word problems |
actions and reactions (3rd law) | pair forces |
What does friction covert energy of motion into? | thermal energy |
What keeps a satellite in orbit around the earth? | force of gravity |
the greater the mass of an object..... | the more inertia the object has |
the law of inertia... | newton's first law |
the friction from air molecules hitting on object moves through the air | air resistance |
statement that describes events or relationships that exist in nature | law |
unbalanced force can keep an object moving in a circle | circular motion |
a force between surfaces that resists the movement of one surface past another surface | friction |
a push or pull | force |
list newton's 3 law of motion | 1 an object at rest stays at rest unless and unbalanced force acts on it
Examples: a book left on the table overnight is there when you return
a soccer ball continues to roll until it hits something
the clothes you left on the floor are still there w |
newton's laws of motion | force = mass x acceleration
a baseball hit with a bat flies farther than a bowling ball hit with a bat |
newton's laws of motion | for every equal and opposite action there is an equal and opposite reaction
a balloon flies forward when air quickly escapes from it |
galileo | Italian scientist showed that falling objects with different masses have the same acceleration |
If you are not strapped into some amusement rides, how would you fly off? | fly off in a straight line |
at the top of a hill on a roller coaster, what does your inertia do to your body? | keeps you there |
