PHYSICS OAT EXAM 2024/2025 WITH GUARANTEED ACCURATE ANSWERS
linear motion--free fall - ACCURATE ANSWERS✔✔ when the ball is
at the max height, the velocity v is 0. The max height the ball reaches
above the ground is found by using:
vf^2=vi^2+2ay
projectile motion - ACCURATE ANSWERS✔✔ obj has a velocity and
position in both vertical and horizontal directions. no acceleration in the
x direction, so particle moves with constant horizontal speed
Force - ACCURATE ANSWERS✔✔ Vector quantity. Units: N
(kg*m/s^2)
F=ma
,mass and weight - ACCURATE ANSWERS✔✔ mass (m)-scalar
weight (w)-force vector
W=mg
unit: N
Newton's laws of motion - ACCURATE ANSWERS✔✔ 1. A body in
motion will stay in motion
2. A net force applied to a body of mass m will result in that body
undergoing acceleration. F=ma
3. For every action there is an equal and opposite re-action
moment of force/torque τ - ACCURATE ANSWERS✔✔ τ=rFsin(θ)
minimum torque occurs when theta=0
centripetal acceleration--does not change the speed of obj - ACCURATE
ANSWERS✔✔ a=v^2/r
centripetal force--magnitude of the centripetal force on a particle -
ACCURATE ANSWERS✔✔ F=ma=mv^2/r
elevator probs - ACCURATE ANSWERS✔✔ while elevator is
accelerating upward, the tension in the cable must be greater than the
maximum weight so that the difference produces a nonzero acceleration.
,while elevator is moving at a constant speed, its acceleration is zero, so
net force on the elevator is also zero, so the tension and weight are
equal.
frictional force - ACCURATE ANSWERS✔✔ Obj sliding down--the
normal force decreases as the angle of the incline increases. frictional
force decreases as the angle of the incline increases
relationship of velocity and time of revolution - ACCURATE
ANSWERS✔✔ v=2πr/T
Box up an incline: solving for perpendicular force - ACCURATE
ANSWERS✔✔ F=mg*cosθ
Box up an incline: solving for parallel force - ACCURATE
ANSWERS✔✔ F=mg*sinθ
Work done by F - ACCURATE ANSWERS✔✔ W=Fdcosθ
Power - ACCURATE ANSWERS✔✔ P=W/t
Unit: Watts (1 J/sec)
P=Force * Velocity
P= Current (I) *V (volts)
, Kinetic energy - ACCURATE ANSWERS✔✔ K=(mv^2)/2
Units: J
Potential energy - ACCURATE ANSWERS✔✔ U=mgh
m=mass of the body
g=gravity
h=height
Units: J
Total mechanical energy - ACCURATE ANSWERS✔✔ E=K+U
-mechanical energy is conserved when the sum of the potential and KE
remains constant
-mechanical energy is not always conserved though. when friction is
present, ME is drained away in heat
work-energy theorem - ACCURATE ANSWERS✔✔ W=ΔK=Kf-Ki
PULLEY efficiency: the measure of the amt of work a person puts into a
machine that comes out - ACCURATE ANSWERS✔✔ Efficiency=W
out/W in
W out=(loadxload distance)
W in=(effortxeffort distance)
load=mass of obj*gravity
