Acceleration is this type of quantity
Vector
100
This quantity is usually on the x-axis
Time
100
This is used to calculate the length of yellow lights at intersections
Stopping Distance
100
The net force on a box that is being pushed with 150N [W], 50N [E], and 100N [W]
200N [W]
200
Mass and time are this type of quantities
Scalar
200
These are the units for acceleration
m/s^2
200
This is non-uniform motion on a distance-time graph
200
The sum of the reaction distance and braking distance
Stopping distance
200
An object in motion will stay in motion, and an object at rest will stay at rest unless acted on by an unbalanced force.
Newton's 1st Law of Motion
300
This is my displacement if I move 150m [N], then 50m [S], then 100m [N]
200m[N]
300
When acceleration and velocity are in the different directions
Slowing Down / Negative Acceleration
300
You can use this on your graph to calculate speed on a distance-time graph
Slope
300
This is the typical reaction time for drivers
1.50s
300
The tendency of an object to resist a change in motion
Inertia
400
This is the formula for velocity
vec v=(∆vecd)/t
400
This is the formula for acceleration
veca=(vecv_f-vecv_i)/t
400
You can use this to find displacement on a velocity-time graph
Area under the curve
400
The stopping distance can be thought of as the length of this for the intersection
Area of no return
400
For every action, there is an equal and opposite reaction.
Newton's 3rd Law of Motion
500
The time is takes for a car moving 40km/h to travel 25m.
2.3s
500
These are the formulas for non-uniform motion
vecd=((vecv_f+vecv_i)/2)t
vecd=vecv_it+1/2vecat^2
500
This is a velocity-time graph with uniform motion
500
The distance travelled when the driver must recognize a need to stop and must move their foot from the gas to the brake pedal.
Reaction distance
500
An object acted upon by an unbalanced force experiences an acceleration in the direction of the force.
