Thank you for the opportunity to help you with your question!

20) Let's begin with the definitions:

a)Force: We can define force as push or pull on an object as a result of its interaction with another object.

b)Acceleration: Rate of change of velocity is known as acceleration.

c)Mass: Mass represents the amount of matter in an object.

d)Weight: It is the force exerted on body by gravity.

21)We have three figures:

Figure 1: To balance the force draw a force of 15N in downward direction.

Figure 2: To balance the force draw a force of 10N acting away from the object in right direction.

Figure 3: To balance the forces draw a 20N force upwards.

22) In the given figure:

Most KE: is at point C

Most PE: is at point A

PE=KE: is at point B

Greatest Mechanical energy: is at point A considering the friction

Energy transformation between A and D: At A it is purely PE but at D it is PE+KE

Please let me know if you need any clarification. I'm always happy to answer your questions.
