Laws of Motion
In this post all the possible objective questions in the lesson Laws of motion is given. Study well and be confident in this lesson to attend the TNPSC group 2,TNPSC group 2A, TNPSC group 4 exam. To prepare well for the TNPSC Group exams we need to study the samacheer text books.
Newton formulated how many laws of motion
What is the branch of physics that deals with the effect of force on bodies
What deals with the bodies, which are atrest under the action of forces
What is the study of moving bodies under the action of forces
What deals with the motion of bodies without considering the cause of motion.
What deals with the motion of bodies considering the cause of motion.
Who stated that a moving body naturally comes to rest without any external influence of the force.
Natural motion is also called Force independant
Violent motion is also called
We have to push or pull or hit an object to change its?
The concept of what is based on this push, pull or hit?
Push, pull or hit may bring objects into?
The one which changes or tends to change the state of rest or of uniform motion of a body is called?
Forces acting on an object which do not change the state of rest or of uniform motion of it are called?
The resultant of two opposite forces acts on an object and brings it to motion.These opposite forces are called?
What arises between two surfaces in contact?
Who observed the motion of objects on an inclined plane.?
The first law of motion is also known as the law of?
The inability of a body to change its state of rest or of uniform motion by itself is called?
Inertia of a body depends mainly upon its?
More massive objects offer?
The impact produced by an object depends on its?
What has both direction and magnitude?
The SI unit of momentum is?
The rate of change of momentum of an object is directly proportional to the applied unbalanced force in the direction of force is called?
The total momentum before collision is equal to the?
The _____ state of all earthly body is either the state of rest or the state of uniform motion.A body in motion will continue to be in the same state of motion as long as no _____ force is applied. When a force is applied on bodies, they resist any change in their state. This property of bodies is called Any body would like to continue to be in its state of rest or the state of motion. This is known as______ The resistance of a body to change its state of rest is called________ The resistance of a body to change its state of motion is called_______ The resistance of a body to change its direction of motion is called _______ An athlete runs some distance before jumping. Because, this will help him jump longer and higher. This is an example of________ When you make a sharp turn while driving a car, you tend to lean sideways.This is an example of_______ When you vigorously shake the branches of a tree, some of the leaves and fruits are detached and they fall down. This is an example of _______ The impact of a ______ is more if the velocity and the mass of the body is more. The ________measures the impact of a force on a body.
Linear momentum is a _____quantity. Two or more forces of equal or unequal magnitude acting along the same direction, parallel to each other are called If two or more equal forces or unequal forces act along opposite directions parallel to each other, then they are called When several forces act simultaneously on the same body, then the combined effect of the multiple forces can be represented by a single force, which is termed as If the resultant force of all the forces acting on a body is equal to zero, then the body will be in equilibrium. Such forces are called A system can be brought to equilibrium by applying another force, which is equal to the resultant force in magnitude, but opposite in direction. Such force is called as A ,______ is a circular wheel with teeth around its rim. It helps to change the speed of rotation of a wheel by changing the torque and helps to transmit power. Force = ____ × acceleration _______is required to produce the acceleration of a body The acceleration is produced along the radius called as ________ The force, which produces this acceleration is called as _______ SI unit of force is ______ The amount of force required to produce an acceleration of 1 ms –2 in a body of mass 1 kg is called _________ In the SI system of units, gravitational unit of force is _______ A large force acting for a very short interval of time is called as_______ _________ is based on the law of conservation of linear momentum as well as Newton’s III law of motion. _____of a body is defined as the quantity of matter contained in the body SI unit of mass is _____ ______of a body is defined as the gravitational force exerted on a body due to the gravity Direction of weight is always towards the ______of the Earth SI unit of weight is _____ The value of acceleration due to gravity on the surface of the moon is_____ Whenever a body or a person falls freely under the action of Earth’s gravitational force alone, it appears to have zero weight. This state is referred to as ______
By studying above lesson Law of Motion you will be able to answer all the possible objective question in this topic during TNPSC group 2 , TNPSC group 4 exam.This article is created by reading every line in the text book.
