Unit 1 – Forces in Fluids
Activity 1
Certain features related to forces in fluids are given.
Buoyancy – When a body is immersed completely or partially in a fluid, the fluid
exerts an upward force on the body.
Factors influencing buoyancy - Density of fluid, volume of body.
Archimedes principle - When an object is immersed partially or completely in a fluid,
the buoyancy experienced by it will be equal to the weight of the fluid displaced by it.
The given table contains the findings of an experiment done by a student by using an overflowing
jar and a spring balance as shown in the figure.

Unit 3 – Motion and Laws of Motion
Activity 1
Newton’s first law of motion : Every object continues in its state of rest or of uniform
motion along a straight line unless an unbalanced external force acts on it.
Inertia : Inertia is the inability of a body to change its state of rest or of uniform motion
along a straight line by itself.
Tabulate the given statements suitabily in the table.
1) Arrange some carrom board coins one on top of the other. Strike the bottom coin forcefully
with a striker then the lowest coin get displaced and all other coins remain stacked.
2) When a moving bus stops suddenly, the standing passengers tends to fall forward.
3) When a bus moves forward suddenly from rest, the standing passengers tends to fall back.
4) Dust in a carpet can be removed by beating the carpet with stick.
5) A running athlete cannot stop himself abruptly at the finishing line in a race.
6) When the branch of a mango tree is shaken, mangoes fall just as when the branch starts
moving.

Newton’s second law of motion
The rate of change of momentum of a body is directly proportional to the
unbalanced external force acting on it
