If the object changes POSITION at a constant rate, it is said to have constant
velocity and zero acceleration - correct answer ✔it is said to have constant
velocity and zero acceleration
If the object changes VELOCITY at a constant rate - correct answer ✔it is
said to have constant acceleration
position-time graph - correct answer ✔slope constant positive A, constant
positive velocity, B stationary, position constantly changing C, accelerating
velocity-time graph - correct answer ✔slope constant positive D, accelerating
constant rate, slope zero E, constant velocity not accelerating, slope negative
F, decelerating, area under graph total displacement
acceleration-time graph - correct answer ✔slope irrelevant, can only
determine acceleration, slope = zero, accelerating constant rate, area under
graph total change in velocity
vector - correct answer ✔requires direction and magnitude
vectors - correct answer ✔velocity, accleration, displacement, force
scalar - correct answer ✔does not require direction
scalars - correct answer ✔mass, time, volume, temperature
, vector must be - correct answer ✔head to tail
projectile motion - correct answer ✔vox=vocos<
range - correct answer ✔r=((vo^2)/g)sin(2<)
angle of rotation - correct answer ✔angular displacement<
angular speed - correct answer ✔w (w=</t)
angular acceleration - correct answer ✔a (a=w/t)
centripetal acceleration - correct answer ✔direction of an object's inward
acceleration causing it to maintain a circular path
1st Law - correct answer ✔stay at rest, stay in motion, unless acted on by
outside force
2nd Law - correct answer ✔force directly proportionals object's acceleration
and inversely proportional mass (f=ma)
3rd Law - correct answer ✔every action, equal and opposite reaction
same force 1 - correct answer ✔large mass, small acceleration
same force 2 - correct answer ✔small mass, large acceleration
