newton's first law
an object in motion will stay in motion until a resultant force acts upon it
newton's second law
a resultant force is needed to make an object accelerate.
in newton's second law the acceleration depends on what
mass of object and size of force
resultant force formula for newton's second law
resultant force = mass x acceleration or F=ma
what is inertia
the tendency of an object to continue at its current motion unless a resultant force acts upon it
what is inertial mass
ratio of force over acceleration
what is velocity
speed in a given direction
is velocity scalar or vector
vector
what is acceleration
change in velocity / time
what is deceleration
the change of velocity per second when an object slows down
the area under a velocity time graph represents distance travelled
what does the gradient of a velocity time graph show
the acceleration
did u get them al correct
yes
