Lavanya is pushing the car but the car is not moving! Why?
She is not putting enough forcee
She is applying force for less duration.
She is applying force but the car is able to push her back equally.
Car is experiencing an opposite force of friction ( which depends on its weight also)

When both forces on an object are same size but opposite direction then the forces are...
Unequal; the object is moving!
Equal; the object is moving!
Balanced and Equal; The object is stationery!
Balanced and Unequal; The object is stationery!

Who ever gets it correct ADD 80,000 Rupees.
Who ever gets it correct the first ADD 10,000 Rupees extra

Friction can be increased by:-
Making the surface rough and big.
Making the surfaces smooth and small.
Greasing with oil!
None of them is true!

When you rub your hands (in winter) how does it become hot?
Explain in terms of particle theory and contact forces!
![Page 29: How to be a millionare questionaire - FORCES!](https://reader034.vdocuments.net/reader034/viewer/2022052606/5a65705d7f8b9af3678b4dcf/html5/thumbnails/29.jpg)
When we increase the contact between our hands by rubbing them again and again, we are increasing the forces of friction which is – the particles in my one hand start to hit the particles in my other hand with such speed that they gain energy and thus generate heat

Speed of falling object depends on what factors?
Gravitational Force
How heavy that object is!
Both A and B
Neither A nor B
![Page 32: How to be a millionare questionaire - FORCES!](https://reader034.vdocuments.net/reader034/viewer/2022052606/5a65705d7f8b9af3678b4dcf/html5/thumbnails/32.jpg)
Speed of any object does not depend on its mass. If this was the case Aeroplanes would not be able to fly at 200km/hr or Rockets at 7.9 Km every second!
Yes the push (force) required to give a rocket this speed is huge! Because force depends on Mass.
