for next class (Friday)

1.  Find a definition for acceleration:  in words and in equation form.

2.  What are the units for acceleration?

3.  If an object starts from rest and achieves a velocity of 8 m/s in 10 seconds, what is the acceleration?

4.  If a car has an acceleration of 1.5 m/s/s, how fast is it traveling after 7 seconds (assuming that it starts from rest)?

5.  What is gravitational acceleration all about?  (Hint:  recall 9.8.....)

6.  If a ball is dropped from rest, how fast will it be traveling after 4 seconds?

7.  If a ball is dropped from rest, how far will it have fallen after 4 seconds?  (This is tricky - find the average velocity first.  We'll soon have equations to make this all easier.)

8.  See if you can find anything about "equations of motion" for homework.

Thanks!
