Q

What is displacement?

A

Where you are in relation to where you started(m)

17
Q

What is average speed?

A

Total distance/total time(m/s)

18
Q

What does a constant slope on a speed vs. time graph tell you?

A

Constant Speed

19
Q

How do you find instantaneous speed?

A

V= change in x/ change in time

ie: find speed at t=5(x value/5sec

20
Q

What is velocity?

A

Displacement/change in time (m/s)

-speed is the magnitude of velocity

21
Q

What is acceleration?

A

Change in velocity/change in time (m/s2)

22
Q

What does the slope of a velocity vs. time graph tell you?

A

m/s2 or acceleration

23
Q

What does the area of a velocity vs. time graph tell you?

A

Displacement

24
Q

What does the slope of an acceleration vs. time graph tell you?

A

Velocity (m/s)

25
Q

What are the 5 KE equations?

A

1: V avg =(Vi -Vf) x 1/2
2: Xf = Xi + 1/2(Vi+Vf) x T
3: Vf =Vi x (T x A)
4: Vf2 = 2A x (Xf-Xi) + Vi2
5: Xf = Xi + Vi(T) + 1/2 (A x T)2
