acceleration and newtons 1 and second law questions

any change in velocity over time is...

• weight

• acceleration

• friction

• normal

factors of acceleration

• starting,stopping,

  speeding up,slowing down,change in direction

• pulling and pushing

• newtons 1 law

• two x two

formula to acceleration

• a=mxf

what is the unit for acceleration??

what is newtons first law?

• an object is always in motion

• an object at rest will stay at rest unless acted upon by an outside force

• and object it always still

• all of the above

more mass=?

• less inertia

• less water

• more speed

• more inertia

what is inertia

• acceleration

• tendency of an object to keep moving the way it currently is

• to have less mass

• to have a greater force acting upon

two things inertia only knows on how to do

• left to right

• right to left

• forward and back

• straight or not moving

what is the acceleration due to earth's gravity?

• 8.9 m/s

• 9.8 m/s/s

• 9.8 m/s

• 8.9 m/s/s

when someone falls what is the only force on that person what is the acceleration for that again?

• 9.8 m/s/s and gravity is the only force being used

• 9.8 m/s/s and friction is the only forced being used

• gravity and 4.5 m/s/s

• appointed and 2.3 m/s/s
