AEM 264 Exam Questions and Answers
Mechanics study of how bodies react to the forces acting on them
statics Study of bodies in equilibrium
Dynamics (kinetics) concerned with the forces causing the motion
Dynamics (kinematics) concerned with the geometric aspects of motion
In dynamics, a particle is assumed to have _______ only a mass
slope of a velocity-time graph= acceleration
velocity-time graph can be constructed by finding the slope at various points along the s-
t graph
acceleration-time graph can be constructed by finding the slope at various points along
the v-t graph
distance moved (displacement) can be calculated by ______ on the v-t graph finding the
area under the curve
, area under the acceleration-position curve represents change in velocity
In curvilinear motion, the direction of the instantaneous velocity is always tangent to the
path
In curvilinear motion, the direction of the instantaneous acceleration is always target to
the hodograph
hodograph A plot of the locus of points defined by the arrowhead of the velocity vector
The horizontal component of velocity remains _________ during a free-flight motion.
constant because there is no acceleration
A particle has an initial velocity v₀ at angle φ with respect to the horizontal. The maximum
height it can reach is when 90
normal component of velocity is __________ always zero
what is not a conservative force frictional force
kinetic energy results from velocity
