Question 1

Displacement is defined as:

Answer 1

How far the object has moved from its starting position and by the direction
Sf= final position
Si= initial position

Question 2

Speed:

Answer 2

Rate of change in linear distance
Distance/ time
SCALAR QUANTITY

Question 3

Velocity:

Answer 3

Rate of change in linear displacement
Change displacement/time
VECTOR QUANTITY

Question 4

Velocity equation

Answer 4

V= position f -position i/
Time at final position- time at initial position

Question 5

Overall Velocity Equation:

Answer 5

Sum of horizontal velocity squared plus sum of vertical velocity squared, then square root

Question 6

First Central Difference Method
(Obtaining velocity from position, using before and after values to get middle value)

Answer 6

V xi = position after - position before/
Position after time- position before time

Question 7

Local Extremum

Answer 7

Where the slope changes, the “apex” basically

Question 8

When creating a position or velocity graph

Answer 8

For velocity, match up quadrants in changes of direction, that’s the +/- change
