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. CBSE Class 9 Science notes for chapter 9 - Force and Laws of Motion are available here. Answer: A ratio of SI units to CGS units of momentum is (kg m/s)/(g cm/s) i.e., 10s. 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. 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. it formula = mass × velocity so it's SI unit is = kg×m/s = kg m/s Hope this helps u thanks skyfall63 skyfall63 SI unit=kg m/s. This is the first part of the notes of Chapter9. Here you will get the CBSE Class 9 Science notes on chapter 11 ‘Work and Energy’. How do you measure the effect of an impulsive force on the body? unit. (c) Rate of change of momentum. Share 2. Force and Laws of Motion Class 9 Extra Questions Short Answer Questions-I. 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. Define linear momentum. What is the full form of SI system? (i) Define momentum. Answer: Define least count of any device. Q2. Define standard unit. Question 1. Linear momentum: Linear momentum of a body is the product of mass of the body and its velocity. Class-9 » Physics. ... sI unit of Power is Joule per second or Js1. Answer 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. The momentum of (P) of an object is defined as the product of its mass (m) and velocity (υ). Free PDF Download - Best collection of CBSE topper Notes, Important Questions, Sample papers and NCERT Solutions for CBSE Class 9 Physics Forces and Laws of Motion. Question 3. (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). What is the ratio of SI units to CGS units of momentum? (iii) Explain how a karate player can break a pile of tiles with a single blow of his hand. So, Linear momentum p = mv. Write its S.I. Answer: The full form of S.I. 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.
