3
Q
What is a scalar?
A
A quantity that only has magnitude
4
Q
What is a vector?
A
A quantity that has magnitude and direction
5
Q
What is the formula for speed?
A
v= d/t speed= distance/time
6
Q
What is the formula for velocity?
A
v=d/t velocity= displacement/time
7
Q
What is acceleration?
A
A change in speed/velocity over time
8
Q
What is the formula for acceleration?
A
a= ^v/^t acceleration= change in velocity/ change in time
9
Q
What is the formula for initial velocity?
A
v1= v2-at final velocity - (acceleration)(time)
10
Q
What is the formula for final velocity?
A
v2= v1+at initial velocity + (acceleration)(time)
11
Q
What is the unit of measurement for acceleration?
A
m/s2
