Question

what is the role of physics in our daily life ?​

Answer 1

1. Air conditioner which we use is a phenomena of physics
2. Fans we use is also because of physics
3. We can watch Television because of the same reason
4. Almost every electric things which gives you comfort is because of physics

Answer 2

1. Physics is the science that enables us to comprehend various natural phenomena that exist in our world.
2. Walking, cutting, watching, cooking, and opening and closing things are all examples of how we use physics in our daily lives.
3. Physics has an impact on our understanding of the world and of man; it is the foundation of all the devices we use; and it allows us to assess the possibilities and limitations of our activities.

Some examples of activities where physics plays a huge role are described below-

1. We can only walk because of physics.

• When we place our foot on the ground, we exert force on it.
• As a result, the ground applies an equal force to our foot, but in the opposite direction, propelling us forward.
• This is known as Newton's third law.

2. We employ physics to open and close hinged doors.

• Torque is the term used to describe the phenomenon of opening and closing doors.
• Torque is the force required to rotate an object around an axis or fulcrum.
• When you open the door clockwise, the torque is positive; when you open it anticlockwise, the torque is negative.

3. In our kitchens, we use physics to prepare delicious meals.

• We use a branch of physics known as "thermodynamics" in the cooking process.
• Thermodynamics is concerned with heat and temperature, which are required for cooking foods.

4. Many physics principles are used when we cut fruits and vegetables.

• We must apply pressure to the knife in order to cut anything.
• The pressure is proportional to the force and inversely proportional to the area.
• As a result, by increasing the pressure on the knife, we can easily cut any object.

5. Seat belts keep us from sliding around inside the car in the event of a collision.

• Our car seat belt operates on the physics concept of "inertia."
• A fast-moving car comes to a halt in an accident.
• As a result, the car's momentum is quickly reduced to zero.
• The seat belt assists in keeping the body from moving forward.
• Because of inertia, our bodies resist stopping.

6. We can't see sound, but we can hear it and feel it.

• Physics here investigates the origin, propagation, and properties of sound using the concept of quantum mechanics.
• Sound is essential for interacting with others, sharing information, creating art, and a variety of other activities.
