2. When a salt/sugar is dissolved in water, salt/sugar particles disappears.
What happens to these particles? What information do you get about the
nature of matter from the above activity?
3. What do you understand by the terms (i) Melting (ii) Boiling
(iii) freezing/solidification (iv) Melting point
4. Name the phenomenon in which particles of two or more substances
intermix on their own? How does it depend on :
a. temperature
b. space between the particles
5. Define kinetic energy.
6. Into how many states is the matter classified physically?
7. List the characteristics of particle of matter.

to a very large volume of water. Which characteristic of particles of matter
is illustrated by this observation?

PHYSICS
ANSWER THE FOLLOWING:
1.What is meant by kinematics?
2. What are scalar and vector quantities?
3. A car travelling at 36km/h speeds up to 72 km/h in 5 seconds. What is its
acceleration? If the same car stops in 20 seconds, what is the retardation?
4.A scooter acquires a speed of 36km/h in 10 s. What is its acceleration?
5. A racing car has uniform acceleration of 4 m/s2. What distance will it cover
in 10 seconds after start?
6. A bus was moving with a speed of 54km/h. On applying brakes, it stopped
in 8 seconds. Calculate the acceleration and the distance travelled before
stopping.
7. A train starting from rest moves with a uniform acceleration of 0.2m/s2 for
5 minutes. Calculate the acceleration and the distance travelled in this time.
8. A train starting from rest attains a velocity of 72km/h in 5 minutes.
Assuming that the acceleration is uniform, find (i) the acceleration (ii) the
distance travelled by the train for attaining this velocity.
9. The brakes applied to a car produce an acceleration of 6m/s2 in the opposite
direction to the motion. If the car takes 2 s to stop after the application of
brakes, calculate the distance it travels during this time.
10. A ship is moving at a speed of 56km/h. One second later, it is moving at
58km/h. What is its acceleration?
11. A body is accelerating at a constant rate of 10m/s2. If the body starts from
rest, how much distance will it cover in 2 seconds?
12. A train running at 108km/h is brought to a halt in 2 minutes. Calculate the
retardation produced by the application of brakes. Also, calculate the distance
train travels before stopping?

three laws of motion?
15.Why do we use seat belts in cars?

21. A batsman hits a cricket ball which then rolls on a level ground. After
covering a short distance, the ball comes to rest. The ball shows to stop
because (a) the batsman did not hit the ball hard enough, (b) velocity is
proportional to the force exerted on the ball (c) there is force a force on the
ball opposing the motion (d) there is no unbalanced firce on the ball so the
ball would want to come to rest.
