... Let’s approximate the Earth as a perfect sphere of radius R♁ = 6,400 km; in this approximation the g-value (acceleration due to gravity) is constant over the planet’s surface: g ≣ fgrav ≣ Fgrav / m = GM♁ / R♁2 = 10 m/s2. Of course the Earth also rotates, at an angular speed that we will label ω and ...

Newton’s Laws of Motion - Wayne State University
... • A reference frame can be considered inertial if a body subject to no external force, moves in a straight line with constant velocity in that frame. • If Newton’s laws are valid in a given reference frame, then they are also valid in any reference in uniform motion relative to that first frame. • A ...

Newton`s Laws
... According to Newton’s second law of motion, the acceleration of an object decreases if its mass increases. The snowball would slow down as it got bigger. Therefore, continually increased force would have to be applied to the snowball to maintain its starting speed. ...

Dynamics of a System of Particles
... Suppose that there are external forces F1 , F2 ...Fn acting on the respective particles. In addition, there may be internal forces of interaction between any two particles of the system. Denote these internal forces by Fik meaning the force exerted on particle i by particle k. The equation of motion ...
