उत्तर

The property by which a body neither changes its present state of rest or of uniform motion in a straight line nor tends to change the present state, is known as inertia.

A batsman hits a cricket ball which then rolls on a level ground. After covering a short distance, the ball comes to rest. The ball slows to a stop because ______.


Name the scientist who gave the laws of motion.


State Newton’s first law of motion. Give two examples to illustrate Newton’s first law of motion.


A plumb bob is hung from the ceiling of a train compartment. If the train moves with an acceleration 'a' along a straight horizontal track , the string supporting the bob makes an angle tan−1 (a/g) with the normal to the ceiling. Suppose the train moves on an inclined straight track with uniform velocity. If the angle of incline is tan−1 (a/g), the string again makes the same angle with the normal to the ceiling. Can a person sitting inside the compartment tell by looking at the plumb line whether the train is accelerating on a horizontal straight track or moving on an incline? If yes, how? If not, then suggest a method to do so.


A force F1 acts on a particle accelerating it from rest to a velocity v. Force F1 is then replaced by F2 which decelerates the particle to rest.


A particle stays at rest as seen in a frame. We can conclude that
(a) the frame is inertial
(b) resultant force on the particle is zero
(c) the frame may be inertial but the resultant force on the particle is zero
(d) the frame may be non-inertial but there is a non-zero resultant force


How does Newton's second law of motion differ from the first law of motion?


Name the different kinds of inertia an object can possess. Give an example of each.


A body of mass 10 kg is acted upon by two perpendicular forces, 6 N and 8 N. The resultant acceleration of the body is ______.

  1. 1 m s–2 at an angle of tan−1 `(4/3)` w.r.t 6 N force.
  2. 0.2 m s–2 at an angle of tan−1 `(4/3)` w.r.t 6 N force.
  3. 1 m s–2 at an angle of tan−1 `(3/4)` w.r.t 8 N force.
  4. 0.2 m s–2 at an angle of tan−1 `(3/4)` w.r.t 8 N force.

Block A of weight 100 N rests on a frictionless inclined plane of slope angle 30° (figure). A flexible cord attached to A passes over a frictonless pulley and is connected to block B of weight W. Find the weight W for which the system is in equilibrium.
