(iii) Explain how a karate player can break a pile of tiles with a single blow of his hand. Filed Under: Class 9, Force and law of motion Tagged With: conservation of momentum, total momentum About Mrs Shilpi Nagpal Author of this website, Mrs Shilpi Nagpal is MSc (Hons, Chemistry) and BSc (Hons, Chemistry) from Delhi University, B.Ed (I. P. University) and has many years of experience in teaching. The momentum of (P) of an object is defined as the product of its mass (m) and velocity (υ). system is International System of Units. (c) Rate of change of momentum. Linear momentum: Linear momentum of a body is the product of mass of the body and its velocity. Define Momentum write its SI unit 2 See answers Brainly User Brainly User Momentum is the quantity of motion of a moving body, measured as a product of its mass and velocity. “Action and reaction are equal and opposite but … (ii) How much momentum will an object of mass 10 kg transfer to the floor, if it falls from a height of 5 m (g =10 m/s 2). Consider the following objects and calculate the magnitude of their momentum in SI units. (i) Define momentum. CBSE Class 9 Science notes for chapter 9 - Force and Laws of Motion are available here. This is the first part of the notes of Chapter9. Share 2. Similarly, small force applied for a long duration will cause the same change in momentum as a large force – Impulse force for a short duration. Answer: Unit is the quantity of a constant magnitude which is used to measure the magnitudes of other quantities of the same nature. Define linear momentum. Write its S.I. Class-9 » Physics. it formula = mass × velocity so it's SI unit is = kg×m/s = kg m/s Hope this helps u thanks skyfall63 skyfall63 Answer: A ratio of SI units to CGS units of momentum is (kg m/s)/(g cm/s) i.e., 10s. Define standard unit. Force and Laws of Motion Class 9 Extra Questions Short Answer Questions-I. Question 3. How do you measure the effect of an impulsive force on the body? The same force acting on the same body for a long duration of time will cause a greater change in its linear momentum as compared to the same for a short duration. Answer: Q2. unit. What is the ratio of SI units to CGS units of momentum? So, Linear momentum p = mv. Question 4. Also write SI unit for each (CBSE 2015) Answer: (a) Initial momentum = mu Final momentum = mv (b) Change in momentum = final momentum – initial momentum = (mv – mu) = m(v – u) SI unit of initial momentum, final momentum and change of momentum is kg m s-1 SI unit of rate of change of momentum is kg m s-2 or N. What is the full form of SI system? Answer Here you will get the CBSE Class 9 Science notes on chapter 11 ‘Work and Energy’.

It is generally a good idea to gain an understanding of the "size" of units. Question 1. P = mυ SI unit of momentum is kg ms-1 Graphs (a) If m = constant P ∝ υ (b) If v = constant P ∝ m. Question 3. SI unit=kg m/s. ... sI unit of Power is Joule per second or Js1. Answer: The full form of S.I. Share with your friends.
