Physics 1st Semester
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
