Simple harmonic motion is defined as a periodic motion of a point along a straight line, such that its acceleration is always towards a fixed point in that line and is proportional to its distance from that point.
Why is it called simple harmonic motion?
The motion of a particle moving along a straight line with an acceleration whose direction is always towards a fixed point on the line and whose magnitude is proportional to the distance from the fixed point is called simple harmonic motion.
Why is SHM important?
Whilst simple harmonic motion is a simplification, it is still a very good approximation. Simple harmonic motion is important in research to model oscillations for example in wind turbines and vibrations in car suspensions.
What are two basic characteristics of SHM?
Solution : The two basic characteristics of a simple harmonic motion : (i) Acceleration is directly proportional to displacement.
(ii) The direction of acceleration is always towards the mean position, that is opposite to displacement.

Answer:
Explanation:
Depression = .75 x 10⁻² m
Load = 120 g
Spring constant = 120g / .75 x 10⁻²
= 160 x 10² g / m
b )
Depression by player
= .48 x 10⁻² m
His weight
= .48 x 10⁻² x 160 x 10² g
= 76.8 kg
So he is eligible.

Answer:
The image distance from right lens is 2.86 cm and image is real.
Explanation:
Given that,
Focal length of left lens = 10 cm
Focal length of right lens = 5 cm
Distance between the lenses d= 15 cm
Object distance = 50 cm
We need to calculate the image distance from left lens
Using formula of lens
Put the value into the formula
We need to calculate the image distance from right lens
The object distance will be
Using formula of lens
Put the value into the formula
The image is real.
Hence, The image distance from right lens is 2.86 cm and image is real.
