Motions Calculations
60 seconds
60 seconds
Involves both speed and direction.
What is velocity
This is the formula used to solve for distance.
What is distance = speed x time
d = s x t
A plane goes from 0 m/s to 500 m/s in 10 seconds.
What is 50 m/s/s
or
50 m/s2
Shift in position (where you started to where you ended up).
Displacement.
This is the formula for Speed.
What is "speed = distance / time"
S = d / t
Your displacement starting at 2 m north, 4 m west, 6 m south, 4 m east.
What is 4 m south?
This is the formula for time.
What is "time = distance / speed"
t = d / s
Position-Time Graph Straight slope, then curves and flattens to no slope.
What is slowing down and then stopping?
Accelerating from 65 m/s to standstill in 10 seconds
What is -6.5 m/s/s? or -6.5m/s2
This is the formula for finding velocity.
What is Velocity = displacement / time
v = d / t
Velocity-Time Graph Downward slope above x-axis.
What is slowing down?
How far you can travel in 10 minutes, moving at 125 meters per minute?
What is 1250 m? (or 1.25 Km).
Your starting point.
What is reference point?
('origin' will also be accepted)
This is the formula used to find acceleration.
What is (final velocity - initial velocity) / time
(vf-vi)/t
(v-u)/t
