Or a more recent example
3 km + 3 km = 6 km
4 km + 7 km = 11 km
8 km - 5 km = 3 km
Finding Distance Using Scalar Addition 1+1+2+3 = 7 km
Finding Displacement using Vector Addition = 5 km NE
Can an object moving with constant speed be accelerating?
Straight,upward line on a V-t graph means constant acceleration
Straight,upward line on D-t graph means constant velocity
Rise/run=slope= 25/5 =
Rise = 25
If you took slope of smaller sections of the graph you would get the same answer since ‘v’ is constant
Run = 5
What is v for 0-1 sec.??
What is v for 0-2 sec.??
What is v for 3-5 sec.??
What is v for 0-5 sec. ??
Ball thrown upward with initial velocity of +30 m/s
