• If a body is moving along a curved path with a constant speed, then the direction of acceleration of the body is perpendicular to the motion of the body.
• Acceleration on a body moving with uniform motion on a circular path is produced due to constant change in the direction of motion
• The movement of gas molecules is irregular
• As soon as a train starts moving, the head of the passenger sitting in it tilts backwards, this is due to the inertia of motion.

Physics Ke Important Question

• If a tanker partially filled with oil is moving with uniform acceleration on a flat road, then the free surface tension of the oil will become in the shape of a parabola due to the force.
• The Earth revolves around the Sun in a fixed orbit (Revolution) due to the force of gravity.

• Brahmagupta had told before Newton that all things are attracted towards the earth.
• Kepler propounded the law of motion of the planets.
• The centripetal force for a satellite to revolve around the planet is derived from the gravitational force of the planet.
• The definition of force is obtained from Newton's first law of motion.
• If the distance between two objects is halved, then the gravitational force between them will be four times already.

• Gravitational force has been mentioned by Newton in his book 'Principia'.
• The orbital speed of a satellite orbiting very close to the Earth's plane is about 8 km/s.
• The orbital period of a satellite orbiting very close to the earth is 1 hour 24 minutes.
• If the Earth starts rotating at a speed 17 times its current angular speed, then the weight of the object placed at the equator will become zero.
• Light energy is transmitted in the form of electromagnetic waves in a vacuum.
• The maximum velocity of light occurs in a vacuum.
• The nature of light rays is dual i.e. both wave and particle.
• The optical gauge works on the principle of reflection of light.
• The photon theory of light was first given by Newton.
• Romer first measured the speed of light.

• It takes about 500 seconds (8 minutes, 20 seconds) for light to reach the Earth from the Sun.
• A few minutes before sunrise, that is, even when it is below the horizon, the reason for the Sun to be visible is the refraction of light.
• Mirage light is due to total internal reflection.
• The endoscope works on the principle of total internal reflection.
• Fiber optics works on the principle of total internal reflection.

• The diffusion of light in the atmosphere is due to the presence of dust particles in the atmosphere.
• The color art of the sky is visible from space.
• The color of the ocean is due to the reflection of the blue sky and the scattering of light by the particles of water.
• Sir CV Raman received the Nobel Prize for the study of the scattering of light rays.
• The red color of light has the longest wavelength.
• A violet colored light is refracted the most when it passes through a prism.
• The determinant of the color of light is the wavelength of the light.
• If a mirror is rotated by an angle of 0, then the reflected ray will rotate by 20 degrees.

• The imaginary line passing through the focus and pole and falling on the spherical mirror is called the principal axis.
• The shadow on the white screen becomes real and big.
• The speed of light is 3×108 m/s.
• Vastu placed between two plane mirrors produces infinite images.
• Concave mirror is used to make grandmother.
• The light ray coming from the Sun can be focused on a point with the help of a concave mirror.
• The angle of incidence for a ray incident on the mirror passing through the center of curvature of a concave mirror will be 00.

• In vehicles, a convex mirror is placed next to the driver to see the rear view.
