Speed is _____________________

Frame of Reference is something ____________________________

How fast are you moving now?

Earth is rotating at _________________________

Earth is orbiting the sun at ____________________

Everything in the universe is _____________________

So, if you drive 55 mph, you are going 55 mph ______________

But the earth is rotating at 1000 mph! So, relative to outer space,

Putting it TogetherQuestions/Main Ideas Main Notes

Let’s use what we know about graphs to make two more formulas.

Let’s look at the graph from ______ to _______

Each time matches up with a _______________

Initial velocity is _____ and final is _____

To find distance traveled between t1 and t2:

Find the __________________________

d = __________________________ + ___________________________

area of rectangle =

area of triangle =

d = a =

d =

8

If you solve for t from first a equation

a = t =

Substitute t into second a equation

d =

a little fancy algebra and solve for vf2

useful if you do not have __________

• use equation 1 only if ________________________

• use equations 2-4 only if ________________________

• Even there are no _____________, they are still all ___________

• vectors mean that ________________ is important

9

• ex. ______________ for up, ______________ for down

Example

A spear is thrown down at 15 m/s from the top of a bridge at a fish swimming along the surface below. If the bridge is 55 m above the water, how long does it the fish have before it gets stuck?
