Question

Which of these does an ideal pendulum experience? Check all that apply.

friction
gravitational
force
normal force
tension
inertia

Answer 1

Gravitational, tension and inertia have the ideal pendulum experience.

Answer: Option B,E,F

Step-by-step explanation:

Ideal pendulum is an object or ball suspended by a thread which will freely vibrate from left to ring and then from right to left and this process repeats continuously.

The rod is suspended by a thread which represents tension, since it is always confined within its region, it is due to inertia, and gravity is the main force acting on all objects in the earth.

Answer 2

For ideal pendulum we will say

The string in that case must be massless and in-extensible

Frictional forces must be zero

there should not be any contact surface of pendulum

Whole mass of pendulum must be concentrated at the center

so above all conditions of pendulum we will say time period is given as

`T = 2\pi \sqrt{(L)/(g)}`

now the correct answer will be

gravitational force

tension

inertia
