What is instantaneous speed |
| Answer» Instantaneous speed is the scalar quantity speed is the distance travelled with respect to time. It shows how fast an object is moved.Instantaneous speed is the motion rate of object at a particular time period or moment. If we take an example of a cheetah who is running with speed of 80 miles per hour then it is instantaneous speed because it is shown as in per hour speed. | |

Difference between gravitational and absolute unit of force. |
|
Answer» The absolute units of force don’t depend upon the value of acceleration due to gravity, so they remain the same throughout the universe. But the gravitational unit of force depend upon the value of ‘g’ which is different at different places. The absolute units of force doesn\'t depend upon the value of acceleration due to gravity, so they remain the same throughout the universe. But the gravitational unit of force depend upon the value of \'g\' which is different at different places.The fundamental difference in convention is that in SI, the constant of proportionality is chosen to be 1, so you have: F = maIn a gravitational system, acceleration is measured in units of g, so you have: F = m (a/g) This allows the same unit to be used for force and for mass. |

What is lamia theorem |
| Answer» It states that if three forces acting at a point are in equilibrium ,then each force is proportional to the sine of the angle between the other two forces. I.e.,A/sin alpha=B/sin bita=C/sin gama. Where A,B,C are three forces and alpha, bita and gama are the angle between forces B and C,C and A,A and B respectively. | |

What is inertia of rest |
| Answer» Inertia of Rest is the tendency of an object (or body) to continue its state of rest unless it is acted upon by an external force. Some of the examples for Inertia at rest are given below: Fruits fall down due to inertia of rest when the branches of a tree are shaken. | |

What is a parallax method ? |
| Answer» To measure large distances, such as the distance of a planet or a star from Earth, astronomers use the principle of parallax. Here, the term parallax is the semi-angle of inclination between two sight-lines to the star, as observed when Earth is on opposite sides of the Sun in its orbit.Parallax is a displacement or difference in the apparent position of an object viewed along two different lines of sight, and is measured by the angle or semi-angle of inclination between those two lines.[Parallax also affects optical instruments such as rifle scopes, binoculars, microscopes, and twin-lens reflex cameras that view objects from slightly different angles. Many animals, including humans, have two eyes with overlapping visual fields that use parallax to gain depth perception | |

What is projectile? |
| Answer» A projectile is any object that once projected or dropped continues in motion by its own inertia and is influenced only by the downward force of gravity.A projectile is any object that is cast, fired, flung, heaved, hurled, pitched, tossed, or thrown. (This\xa0is\xa0an informal\xa0definition.) The path of a projectile is called its trajectory. Some examples of projectiles include a baseball that has been pitched, batted, or thrown .\xa0 | |

Why rainbow is created in the sky |
|
Answer» Rainbow is caused by refraction, total internal reflection, and dispersion of sunlight through water drop present in atmosphere Rainbow is a combination of refraction, dispersion and total internal reflection of sunlight. In sky, prism like objects are needed for the dispersion of light. After rainfall, tiny water drops suspended in air act as prisms. The rainbow\'s appearance is caused by dispersion of sunlight as it is refracted by (approximately spherical) raindrops.The light is first refracted as it enters the surface of the raindrop, reflected off the back of the drop, and again refracted as it leaves the drop.Their colors come from raindrops that reflect sunlight, breaking white sunlight into colors .\xa0Sunlight is made up of many wavelengths so that makes us see the colors of the rainbow.When the light enters the water, it bends causing its shape.\xa0 |

Friction force |
|
Answer» It is the resistance that one surface or object and counters when moving over another. Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other.Friction is the resistance to motion of one object moving relative to another. It is not a fundamental force, like gravity or electromagnetism. |

What is collision ? |
|
Answer» Interaction between two Bodies or their fields is called as collision Collision is an event in which two or more bodies exert forces on each other for a relatively short time. Collision is short-duration interaction between two bodies or more than two bodies simultaneously causing change in motion of bodies involved due to internal forces acted between them during this.Examples:-An insect touches its antenna to the leaf of a plant. The antenna is said to collide with leaf.When a boxer throws a punch, his fist is said to collide with the opponent\'s face |
