Acceleration is this if the object is moving at a constant speed.
What is zero.
100
This is on the x-axis.
What is time
100
This is solved with the equation (final velocity - initial velocity) / Time

to the left
300
Acceleration is _______________ when speeding up in the negative direction.
What is negative
300
This determines acceleration
