AEM 264 Exam Questions and Answers 100% Verified
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
Average speed is defined as total length/change in time
Total distance traveled positive scalar
represents the total length of the path over which the particle travels
Velocity rate of change in the position of a particle
is a vector (has both a mag and a direction)
, Magnitude of velocity is speed
average velocity change in displacement/change in time
Acceleration The rate at which velocity changes
vector (has both a mag and a direction)
instantaneous velocity/acceleration derivative
Acceleration is positive? False, can be positive (speeding up) or negative (slowing down)
a(ds)= v(dv)
postion='velocity=''accel
s= s₀+v₀t+(1/2)at²
v²= 2as+v₀²
average accel= (v2-v1)/(t2-t1)
