Question

ICSE 10th physics
Chapter 1
Forces : Turning Forces and Uniform Circular motion
Explain the important topics to study in the chapter.....

Answer 1

First of all numericals are important.
Then i am giving u the important questions that u need to study..
1) Translational motion and rotational motion(definition).

2) What is moment of force or torque and the factors affecting it.

3) Definition and direction of clockwise and anticlockwise moment of force.

4) What is a couple and state its effect.

5) What is moment of couple and derivation of a relation for it.

6) Equilibrium of a body and its types(definition).

7) Conditions for a body acted upon by several forces to be in equilibrium.

8) What is the principle of moments.

9) Define the centre of gravity of a body and state a factor on which it depends.

10) Learn the position of situation of centre of gravity of some bodies(for e.g., circular ring, solid cone etc.)

11) Difference between uniform circular motion and uniform linear motion.

12) Centripetal force and centrifugal force(Definition and direction of action)

And then some of the give reasons, like -
1. Why is it easier to open the door by applying the force at the free end of it?

2. In a beam balance when the beam is balanced in a horizontal position is said to be in static equilibrium. Give reason.

3. The rain drops reaches the earth surface is in dynamic equilibrium. Give reason.

4. A uniform circular motion is an accelerated motion. How ? ( with diagram)

5. Explain the motion of a planet around the sun in a circular path.

This will be enough for this chapter.
Hope this helps u..
