What is newton\'s three laws of motion |
|
Answer» The first law of motion= it is state that if a body is in motion it will remain in motion or if a body is in rest it will remain in rest until an another force is not applied on it.The second law of motion=it is state that the rate of change of momentum is directly propostional to the force applied on it.The third law of the motion=it is state that the every action is an equal and opposite reaction The first law of motion is: an object /body is at rest remains at rest or an object /body is at motion continue in motion The second law of motion : the rate of change in momentum is directly proportional to applied the forceThe third law of motion : third law motion said to be every action is equal and opposite reaction The first law of motion is stated as: An object remains in a state of rest or of uniform motion in a straight line unless compelled to change that state by an applied force.The second law of motion states that: the rate of change of momentum of an object is proportional to the applied unbalanced force in the direction of forceNewton\'s third law of motion states that: Whenever a body exerts a force on another body, the second body exerts an equal and opposite force on the first body |

what acceleration due to gravity |
|
Answer» The acceleration produced in a freely falling body under earth\'s gravity(with no force acts on it) called acceleration due to gravity, g. When an object falls freely towards the earth there happens to be no change in the direction of motion of the object but due to the attraction of earth there will be a change in the magnitude of velocity. Change in velocity involves acceleration. So whenever the objects falls towards earth an acceleration is involved due to earth\'s gravitational force. This acceleration due to earth\'s gravitational force is called acceleration due to gravity which is denoted by \'g\' and its unit is m/s2. |

define law of conservation of momentum |
|
Answer» • It states that momentum can neither be created nor destroyed. \tLaw of conservation of linear momentum is a extremely important consequence of Newton\'s third law of motion in combination with the second law of motion.\tAccording to law of conservation of momentum: When two or more bodies acts upon each other their total momentum remains constant provided no external forces are acting\tSo, Momentum is never created or destroyed. |

what is difference between velocity and speed |
| Answer» \tS.No. Speed Velocity1.It is defined as the rate of change of distance.It is defined as the rate of change of displacement.2.It is a scalar quantity.It is a vector quantity.3.It can never be negative or zero.It can be negative,zero or posituve.4.Speed is velocity without direction.Velocity is directed speed.5.Speed may or may not be equal to velocity.A body may possess different velocities but the same speed.6.Speed never decreases with time. For a moving body, it is never zero.Velocity can decrease with time. For a moving body , it can be zero.7.Speed in SI is measured in ms-1Velocity in SI, is measured in ms-1\t | |

Why a truck or a motorbus has much wider tyres |
|
Answer» The truck and motor bus has wider tyres because as more the area less the pressure . as the area increase the pressure will decrease , so there will be less need to apply more pressure to handle the vehicle ....the vehicle will move smoothly A truck or motor bus has much wider tires to reduce the pressure exerted by it as more the area more will be the pressure exerted and less the area less will be the pressure exerted.The truck and motorbus have wider tyres with respect to the property that "more the area ,less the pressure." As the area is more the pressure will decrease , so there will be less need for applying more pressure to handle the vehicle.The vehicle will move smoothly. |
