Inertial masses are found in Newton's second law. m1 and m2 are gravitational masses.
True or False:
a) In the Newton's law of gravitation, F = Gm1m2/r2, the masses m1 and m2 refer to inertial masses.
b) For a cart moving along a track, with the x-axis parallel to the track, only the x-coordinate of the cart can change.
c) If the cart is moving on the positive x axis, the x-component of velocity must be positive.
