🌷1.4 Elasticity

Elasticity
👉The property of material that enables an object to return to its original shape and size after the force applied on it is removed

Hooke's Law
👉The extension of spring (x) is directly proportional to the force applied on the spring (F) provided the elastic limit of the spring is not exceeded

k is spring constant

F=kx

Important Definitions !

🌷Chapter 1 - Force and Motion II

1⃣Weight
👉The gravitational force acting on an object

2⃣Force
👉A push or pull upon an object

3⃣Resultant Force
👉The single force that represents the vector sum of 2 or more forces acting on an object
👉The total force acting on the object

4⃣Free body diagram of an Object
👉Diagram that shows all the forces acting on that object only

5⃣Newton's 2nd Law of Motion (F=ma)
👉The rate of change of momentum is directly proportional to the force
👉Acts in the direction of the applied force

6⃣Acceleration (a= v-u / t)
👉Rate of change of velocity

7⃣Resolution of Forces
👉The process of resolving a force into 2 components
- Vertical and horizontal

8⃣Equilibrium of Forces or (Forces in Equilibrium)
👉The force acting on it produce a zero resultant force

9⃣Elasticity
👉The property of material that enables an object to return to its original shape and size after the force applied on it is removed

🔟Hooke's Law
👉The extension of a spring (x) is directly proportional to the force applied on the spring provided the elastic limit of the spring is not exceeded.

🔹The Formation of Embryo Sac in an Ovule 🥚🌺

➤ Ovule is formed from an ovarian tissue. Each ovule contains one megaspore mother cell (2n). [2m]
➤ The embryo sac mother cell (2n) undergoes meiosis to form 4 haploid megaspore cell (n). [2m]
➤ Three megaspores degenerated and only one megaspore will continue to develop. [1m]
➤ The remaining megaspore undergoes mitosis three time to form a with eight nuclei. [2m]
➤ Three cell move to one end near to micropyle, forming two synergid cell and one egg cell. [1m]
3 cell = 2 synergid + 1 egg
➤ Three more cells move to another end to form three antipodal cell. [1m]
➤ One cell with two nuclei located at the center to form polar nuclei. [1m]
➤ The structure formed is known as embryo sac which is protected by integument. [1m]
