Answer 2

Answer:

6. a) Friction between any two surfaces in contact is the force that opposes the relative motion between them The force of limiting friction (F) between any two surfaces in contact is directly proportional to the normal reaction (R) between them F prop R or F = mu R where mu is coefficient of limiting friction

c) Force is defined as the rate of change of momentum. For an unchanging mass, this is equivalent to mass x acceleration. So, 1 N = 1 kg m s-2, or 1 kg m/s2.

d) a body is said to be motion when its position is changed continuously with respect to a fixed position with the time there are two types of motion uniform motion anc non uniform motion

e) Descending Order. Arranging numbers (or other items) in descending order means to arrange them from largest to smallest. The numbers 12, 5, 7, 10, 1, 160 arranged in descending order are 160, 12, 10, 7, 5, 1.
