... 16. A steel ball whose mass is 2.0 kg is rolling at a rate of 2.8 m/s. What is its momentum? p = mv = (2.0 kg)(2.8 m/s) = 5.6 kg*m/s 17. A race car leaves the starting line and travels 36000 m in the first 600 seconds of the race. They are then forced to take a pit stop and don’t go anywhere for 250 ...

... Using Newton's Laws Fighting Over a Toy Are the units correct? m/s2 is the correct unit for acceleration. Does the sign make sense? The acceleration is in the positive direction because Anudja is pulling in the positive direction with a greater force than Sarah is pulling in the negative direction. ...

... What is Newton’s Third Law of Motion? • Newton’s third law states: Whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first. • In other words, all forces act in pairs. • Action and reaction forces are present even when there is no motio ...

Newton`s Laws of Motion - pams
... Newton’s First Law: Objects in motion tend to stay in motion and objects at rest tend to stay at rest unless acted upon by an unbalanced force. Newton’s Second Law: Force equals mass times acceleration (F = ma). Newton’s Third Law: For every action there is an equal and opposite reaction. ...

F12 = Gm1m2/R2 and Fc = m1vc2/R, so Gm1m2/R2 = m1vc2/R Gm/a = v2 (I substituted “a” for “R”, as in Kepler’s Third Law) Since P =2πa/v, ...
