MCQ & Solution - Force and Laws of Motion, Science, Class 9 | EduRev Notes notes for Class 9 is made by best teachers who have written some of the best books of Answer The velocity with which a gun moves backward after firing a bullet is called the recoil velocity of a … Newton’s first law gives the qualitative study of force which states that everybody remains in its state of rest or of uniform motion, unless it is compelled by an external force. According to the principle of inertia, the object continues in its state of motion unless a force acts on it. This enables the goalkeeper to: (a) Exert large force on the ball (b) Increases the force exerted by the ball on hands (c) Increase the rate of change of momentum (c) Inertia of rest keeps the upper part of body at rest whereas the lower part of the body moves forward with the horse. to change by itself the state of uniform motion in a straight line. Which one of the following statements is not correct for an object moving along a straight path in an accelerated motion? Hence , we found that Rate of change of momentum is equal to Force applied on the object . (a) Unable to change by itself the state of rest. acceleration, Question.15: When a net force acts on Activity 9.5 asks us to tie an inflated balloon with a straw, put a string inside the straw and check the movement of the ballon. (a) In the direction opposite to the direction of motion of bus. The inertia of a body depends upon mass of the body.

For best view of this site use Google Chrome, Question.1: If a bus starts suddenly, Friction between any two objects is caused due to the interlocking of irregularities present on the surface that are in contact. 1. Class 9. An object of mass 2 kg is sliding with a constant velocity of 4 m/s on a friction less horizontal table. (b) Unable to change by itself the state of uniform motion in a straight line. Then the force involved is. The question states an accelerated motion of an object along a straight line, this implies a non zero force is acting on the object, which is increasing its velocity and speed. Statics is the branch of mechanics which deals with the study of the objects in equilibrium that are under the action of external forces. The rate of change of momentum of an object is proportional to. (c) is correct. 1 When a car suddenly takes a turn, the passengers are thrown in the outward direction due to inertia of direction. to change by itself the direction of motion. (c) Inertia … Due to inertia of motion, the body continues moving with uniform velocity without any external force.
