If the velocity and acceleration have the same sign, then speed is _______________________
Increasing
A definitive integral will have a ______________ as an answer. The # represents the change in ______________ over the time interval. By the Fundamental Theorem of Calculus, since v(t)=x'(t), the integral will yield x(t2) - x(t1). This is also known as ________________________. The answer can be positive or negative depending on if the particle lands to the left or the right of its initial starting position.
Number; position; displacement
An indefinite integral is an expression for _____________ at time t. Don't forget that you will have a _______________, the value of which can be determined if you know a position value at a particular time.
Position; constant
To find the change in _______________ integrate velocity of the time interval. This is also called ________________________.
Position; displacement
To find the total distance travelled, integrate _______________ ,which is the ____________________________ of velocity
Speed; absolute value
To find a new position of a particle moving along the x-axis, add _________________________ to the integral of ______________ from starting time to new time
Starting position; velocity
An absolute value of a definite integral is a number. This number represents the ________________________________ traveled by the particle over the time interval. The answer should always be ____________________.
Total distance; non-negative
Speed is the absolute value of _________________
