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)

Friction is a force that :-

Stops moving objects!

Slows Down moving objects!

Help us walk!

All of them are true!

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!

Draw a force Diagram for a girl holding a book. (Book is stationery –still- not falling)

Who ever gets it correct ADD 80,000 Rupees.

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

Rs. 80,000 +10,000

Select the FALSE statement:

Forces can change movement of objects

Forces can change Direction of Objects

Forces can change shape of an object!

All of them are true!

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!

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

VIDEO Question (Watch the video and answer the question in the next slide)

Speed of falling object depends on what factors?

Gravitational Force

How heavy that object is!

Both A and B

Neither A nor B

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.
