16
Q

How do you tell if an intergral is definite or indefinite?

A

Indefinite intergrals are finished with ā€œ+cā€

Definite intergrals have values before the intergration symbol

17
Q

What is the formula for finding displacement from velocity?

A

s = (intergrate)v dt

18
Q

What is the formula for finding velocity from acceleration?

A

v = (intergrate)a dt

19
Q

What is the value used for acceleration caused by gravity?

A

g = 9.8 ms^-2

Use this value unless the question states otherwise.

20
Q

How is de-acceleration shown?

A

The acceleration has a negative value.
