What is Net Force?
|
When two or more forces act on an object at the same time.
|
|
|
|
What is Balanced Force?
|
Equal forces on a object in size and in opposite direction.
|
|
|
|
What is a Unbalanced Force?
|
Forces on an object that are un-equal in stregenth, and opposite in direction.
|
|
|
|
What is Inerita?
|
The tendency of an object to resist any change in it's motion.
|
|
|
|
What is Newton's First Law?
|
A object at rest stays at rest, unless a net force acts upon it.
|
|
|
|
What is Newton's Second Law
|
Basically, where you throw it is where it goes, and how hard you throw it is how fast it accelrates.
|
|
|
|
What is the equation for accelration?
|
Accelration=Net Force/Mass.(M=F/A)
|
|
|
|
What is Sliding Friction?
|
The force that opposes the motion of sliding objects.(Moving)
|
|
|
|
What is Static Friction?
|
The friction between two surfaces that are not moving.
|
|
|
|
What affects Air Resistance?
|
Speed, Size, and Shape
|
|
|
|
In what range does air resistance affect.(e.x. United States, Earth, Moon)
|
Air resistance affects everything in the Earth's Atmosphere.
|
|
|
|
What determines how fast objects fall?
|
The mass of objects and the distance between objects.
|
e.x. shape
|
|
|
What is Newton's Third Law?
|
For every action, there is a equal and opposite reaction.
|
|
|
|
What is the dirrerence between Mass and Weight.
|
Weight is a force, and Mass is a measurment of the amount of matter a object contains.
|
|
|
|
What is Momentum affected by?
|
Momentum is affected by speed and mass. (Momentum's equation is Momentum=Mass* Velocity.(P=M*V))
