What is Position
describes the location of an object
is a location for which you compare other locations
the measure of how far something moves
A reference point is
describes the location of an object
The change in position over time
Is the location to which you compare other locations
what is Motion
Is a change in position over time
the measure of how far something moves in an given amount of time
when something stops
what is speed
speed is the measure of how far something moves in a given amount of time.
running
speed is the quantity that has both size and direction
speed is speed in a specific direction
What is the formula for speed
S=D/T
S = D x T
S = T x D
S = V x T
What is a vector
vector is speed in a specific direction
Vector is the quantity that has both size and direction
Vector is your average speed
Vector is hydro flask sksksksk
what is velocity
Velocity is the average time running
Velocity is speed in a specific direction
Velocity is a location to which you compare other locations
What is Acceleration
Acceleration is acceleration in circular motion
Acceleration is decrease in velocity
Acceleration is the rate at which velocity changes
Acceleration is jogging
what is the formula for acceleration
V2 -V1 / T
V-V
A= V- V / T
Centripetal acceleration is
decrease in speed
In crease in speed
Acceleration in circular motion
what is positive acceleration
increasing speed
decreasing speed
Running backwards
Hugging
negative acceleration is
decrease in velocity
increase in speed
decrease in speed
increase in velocity
what is force
a push or pull
falling
turning
what is the unit to express force
A
E
F
N
what is contact force
Magnetic force
gravity
A force exerted during contact between objects (friction)
Distance force
Acts in gravity and a magnetic force
friction
arrows
what is net force
balanced force
unbalanced force
the combination of all the forces acting on a object
what is the formula for when net force for objects that act in the same direction
G + G + N
N+ N = N
F + N = N
S + D = N
what is the formula for when the net force in opposite directions
N - N = N
F - F = G
2 + 2 = 4 - 3 = 1 quick Maths
