Question
1) a. A mass attached to a spring is moving is SHM and its speed is decreasing. What is happening to its acceleration during this interval? b. What force is directly responsible for the tangential (linear) acceleration of a pendulum bob? How can it cause different accelerations at different points of it is a constant-magnitude force? c. Which force is directly responsible for the acceleration pattern of a mass oscillating at the end of a spring? Describe the characteristics of this force that produces the acceleration pattern experienced by the mass? 1) a. A mass attached to a spring is moving is SHM and its speed is decreasing.

Which force is directly responsible for the acceleration pattern of a mass oscillating at the end of a spring? Describe the characteristics of this force that produces the acceleration pattern experienced by the mass?Explanation / Answer
a)
SInce speed is decreasing, acceleration must be acting in opposite direction of speed and it s magnitude will be increasing
b)
gravitational force is responsible for tangential acceleration
It causes different acceleration as the angle between this force and tangent keeps changing as bob oscillates
c)
spring force = -K*x is responsible for mass oscillating at the end of spring
This force keeps changing as x changes. So force here is not a constant force
It keeps changing always
