9th Class Physical Science 2nd Lesson Laws of Motion 1 Mark Important Questions and Answers<\/h3>\n

Question 1.
\nCalculate the momentum of a fast moving ball with a velocity 2.2 m\/s of mass 6 kg.
\nAnswer:
\nmass (m) = 6 kg
\nvelocity (v) = 2.2 m\/s
\nmomentum = mv = 6 \u00d7 2.2 = 13.2 kg.m.s-1<\/sup>
\nThe momentum of a fast moving ball is 13.2 kg ms-1<\/sup>.<\/p>\n

Question 2.
\nWhat is Newton’s first law of motion?
\nAnswer:
\nEvery object will remains at rest or in a state of uniform motion, unless compelled to change its state by the action of a net force.<\/p>\n
