Vocabulary
100
Gravity pulls things to the core of the Earth
What does gravity do?
100
As an object slides a surface and slows down
What is When can you observe friction?
100
How fast an object is moving
What is speed?
100
It's a force that acts at a distance
What kind of force is magnitism?
100
Is the product of mass mulitiplied by velocity
What is Momentum?
200
A pulling force
What is Gravity?
200
Wouldn't be able to slow down
What would be an effect of no friction?
200
It can affect it by an unbalenced force changing the motion and direction
How can weight affect how fast an object goes?
200
It is changed in positon over time
What is motion?
200
It is the change in volocity over time
What is Acceleration
300
It keeps the moon moving around the Earth
What does Earth's gravity affect on the moon
300
A force that rub and it gradually slows it down
What is friction?
300
Divide the distance travled by the time spent travling.
What is the measurement of speed?
300
Because of Earth's magnitism
Why does the needle of a compass move?
300
Often pointed in the opposite directions, and they always add up to zero
What is Balanced Forces?
400
Because it has such a large mass
Why does gravity cause the tides?
400
Lubricant like oil, wax, grease, or by making surfaces smoother
How can friction be reduced?
400
It is a push force
What type of force is speed?
400
They repel
What happens when opposite poles of magnets are near each other?
400
A force that causes an object to change its motion
What is Unbalenced Force?
500
Who's theory was it to come up with Universal Gravitation
Who is Sir Isaac Newton?
500
It slows it down depending on the tires.
How does different tires affect the amount of friction?
500
Is the measurement that combines both speed and direction of a moving object
What is Velocity?
500
They repel
