WebP10.4 Momentum AQA GCSE Physics Force And Motion Kerboodle Answers: Page No. 151. 1 a Momentum is the quantity of mo-tion of a moving body, measured as a prod-uct of its mass and velocity. Its unit is mo-mentum = mass(kg)*velocity(m/s) = kg-m/s. b momentum of 340kg person runn-ing at 6n/s, = 40*6 = 240kgm/s. Cambridge IGCSE … WebCharging by Friction. When certain insulating materials are rubbed against each other they become electrically charged. This is called charging by friction. The charges remain on the insulators and cannot immediately flow away. One becomes positive and the other negative. An example of this is a plastic or polythene rod being charged by rubbing ...

Web9. Plot the graph of the kinetic friction (f k) against the normal force (R). Since f k = μ k R, find the value of coefficient of kinetic friction (μ k) from the graph. The slope of the straight line = 0.26. Repeat steps 5 to 9 by replacing the wooden block with the bricks. Find the values of μ s and μ k for the ... WebThe symbol usually used for the coefficient of friction is m. The maximum frictional force (when a body is sliding or is in limiting equilibrium) is equal to the coefficient of friction × the normal reaction force. F = m R.
