1.As a body falls from a certain height its velocity _______________________.

2. The more _________ a solid is, the greater force is needed to deform it.

3.No ________ is done on a body, if the displacement is perpendicular to the direction of force.

4.The greater the ____________ of a liquid, the grater is the pressure it exerts.

5.Gold is ___________ because it can be hammered into very fine sheets without breaking

6.Copper is __________ because it can be drawn into very fine sheets without breaking

7.A raised hammer has __________ energy.

8.As a body rises up, its velocity _____________.

9.Kinetic energy is energy in ______________.

10.The greater the air friction, the less is the ___________ of a body falling from a certain height

Answer 1

1. As the body fall from a height it's potential energy converts into kinetic energy hence veloctiy is increased.

answer- increased.

2. Elastic

3. Work done on a particle is given by   or   if displacement is perpendicular then theta will be 90 degrees and cos90 is zero. Hence no work done

answer - work

4. pressure of a liquid is given by   when height / depth increase pressure also increase.

answer- depth

5. Malleable

6. Ductile

7. Potential

8. Decreases

9. Speed

10. Speed
