What would happen to the egg if there was no gravity?

 would float into space

200

Which force slows down the egg as it falls?

 air resistance

200

What type of energy does potential energy transforms when the egg starts falling?

 kinetic energy

200

Which will Fall faster: An egg or a feather? and Why?

egg 

- It is heavier

 impact force

400

When the egg breaks, what happens to its energy?

 transformed into sound energy

400

In a vacuum with no air, which will fall with more speed- feather or a rock? and Why?

Both fall at same speed because no air resistance
