Ans​

Answer 1

Answer:

1.) If you pull a weight on a spring down and let it go, then it will oscillate around its mean position in what is called harmonic motion. Rather surprisingly, this is exactly identical to another fundamental motion: the -coordinate of a particle which moves around a unit circle uniformly at a constant speed.

Explanation:

2.) A blacksmith hammers a hot piece of iron while making a tool. How does the force due to hammering affect the piece of iron? Answer: The force is applied due to hammering causes the change in shape of iron and iron can be moulded in the shape of the required tool.

Answer 2

Explanation:

1. This is to signify that the restoring force due to the spring is in the opposite direction to the force which caused the displacement. Pulling down on a spring will cause an extension of the spring downward.

2. Hammering.
