For two vectors to have their sum equal zero, they must be equal.

If two vectors have unequal magnitude can there some be zero?

Speed- #of units

Velocity- includes direction

Velocity- includes direction

What is the relationship between instantaneous speed and instantaneous velocity

30 m/s east

What is another way of saying -30 m/s west

No

Is it possible to add a vector quantity to a scaler quantity

When they’re in the same direction

if B is added to A, under what conditions does the resultant have the magnitude equal to A+B?

Yes because you’re back where you started

If a set of vectors laid head to tail forms a close polygon, the resultant is zero. Is this statement true?

Yes example is a cat climbing up a tree

Can you vector have a component equal to zero and still have a nonzero magnitude?

No

Can a vector have a component greater than its magnitude

in vector resolution you were breaking the hypotenuse into components

Explain the difference between vector addition and vector resolution

Perpendicular to each other

If the component of one vector along the direction of another is zero what can you conclude about these two vectors?

Law of cosines

How would you add to vectors that are not perpendicular or parallel

Equal and opposite

If A+ B=0 p, what can you say about the components of the two vectors?

45, 45,99 triangle

Under what circumstances would a vector have components that are equal in magnitude

Displacement is zero

– forms triangle

-could all be on same line

– forms triangle

-could all be on same line

The vector sum of three vectors gives a resultant equal to zero what can you say about the vectors

It will head right next to mass because the rock is moving too.

If a rock is dropped from the top of the sailboats mass will it hit the deck at the same point where the boat is at rest or in motion a constant velocity
