dumbass formuals you need to remember Flashcards
motion
change in position of body in relation to time
linear motion
movement in a straight line
retalinear motion
the movement of an object along a straight line,
force
mass x acceleration
displacement
intial minus - final position
speed
rate of motion
distance over time
velocity
rate of speed of which object moves position
displacement over time
linear acceleration
rate of velocity change over time
final velocity- intial
ovet time
momentum
mass x velocity
conservation of momentum
momentum of object remains constant before and after collision
mass x velocity
force summation
lot of body parts to make more force
impulse
force x time
change in momentum
torque
force on applied to outside body centre of mass
force x movement arm
angular momentum
how much rotation something has
moment of inertia x angular velocity
angular speed
angular distance covered over time taken
change in angular distance over time
angular velocity
how fast an object rotates
intial angle - final angle over time
angular acceleration
rate of change of angular velocity
final - intial over time
angular displacment
smaller of two angles
difference in degrees in body parts
conversation of angular momentum
airbourne object HAS NO ANGULAR MOmentum
moment of inertia
mass of object resistant to chnage of rate of rotation
mass x radius
