What is motion very short answer?
Answer: In physics, motion is a change in position of an object with respect to time. Motion is typically described in terms of displacement, distance (scalar), velocity, acceleration, time and speed.
What is Motion answer in one word?
In physics, motion is the phenomenon in which an object changes its position over time. Motion is mathematically described in terms of displacement, distance, velocity, acceleration, speed, and time.
What is Motion answer for Class 6?
Answer:
| Rotational motion | Circular motion |
|---|---|
| It is the motion of an object about an axis and its different parts move through different distances, without any change in its position. | It is the motion of an object in a circular path and its position changes continuously. |
What is distance in science class 6?

How are clouds formed Class 6?
The process of evaporation followed by condensation causes the formation of clouds. On reaching a certain height, water vapour present in air condenses to form tiny droplets of water. These water droplets collect to form clouds that float in air.
How are shadows formed Class 6?
Shadows are formed when light is stopped by an object. An opaque objects stops the light completely, so an opaque object casts a dark shadow behind it. A shadow is formed when an opaque object comes in the path of light and stops it. An object forms shadow on the opposite side to the source of light.
Can you see light if not why Class 6?
Answer: The objects which have light of their own are called luminous objects such as torch, bulb, burning candle, etc., whereas non-luminous objects does not have light of their own and can be seen only when light falls on them such as table, wall, book, etc.
What do you need to see a shadow class 6?
(1) There should be an opaque material. (2) There should be a source of light and screen. The object must be placed in the path of light. Then shadow is formed on the screen.
What is the path of light Class 6?
In a pinhole camera, image formed is inverted because the object is between radius of curvature and focus. What is the path of light? Answer: Straight line.
What is umbra and penumbra Class 6?
(i) Umbra means ”shadow” while ”penumbra” means to hang on the shadow or almost a shadow. The outer shadow of the earth falls on the moon during a penumbral lunar eclipse.
What happens when light falls on a mirror Class 6?
An image can be seen in the mirror because the light reflected from an object falls on the mirror and it is reflected. So, light incident on any smooth shiny surface like a mirror bounces back into the same medium. This bouncing of light by any smooth surface is called reflection of light.
What does the mirror do when light falls on it?
When light falls on a mirror, it changes the direction of light. This phenomenon is called the reflection of light.
What do we need in order to see a shadow?
we can easily observe the shadow of an object. But in night time, when there is no light, we are unable to observe our shadow. In night time, a light source can make a shadow visible. So, Opaque objects and a light source are the main requirements to see a shadow.
Are plane mirror images always upright?
Summary. A plane mirror always forms a virtual image (behind the mirror). The image and object are the same distance from a flat mirror, the image size is the same as the object size, and the image is upright.
When two plane mirrors are kept at 90 degree we get?
When you place two plane mirrors at a 90-degree angle, the image of the first mirror is reflected in the second mirror so that the reversed mirror image is reversed again, and you see a true image. (See Glossary, page 73.)
Why real images are inverted?
A real image occurs where rays converge, whereas a virtual image occurs where rays only appear to converge. Real images can be produced by concave mirrors and converging lenses, only if the object is placed further away from the mirror/lens than the focal point and this real image is inverted.
How is your image in a plane mirror different from the real you?
An image formed by reflection may be real or virtual. A virtual image is right side up (upright). In flat, or plane mirrors, the image is a virtual image, and is the same distance behind the mirror as the object is in front of the mirror. The image is also the same size as the object.
Why can’t a plane mirror form a real image?
The image formed by a plane mirror is always virtual (meaning that the light rays do not actually come from the image), upright, and of the same shape and size as the object it is reflecting. Virtual objects produce real images, however. The focal length of a plane mirror is infinity; its optical power is zero.
How can you prove to someone that an image is a real image?
In a convex lens, the image is real if the distance of the object from the lens is greater than the focal length and virtual if it is less than the focal length. If the object is at the focus the image is formed at infinity.
Why do we look different on a plane mirror?
Our eye and brain interpret any light rays that enter an eye as having traveled in a straight line path. For a plane mirror, the image will be the same size as the object and will be the same distance behind the mirror as the object is in front of the mirror.
