Instantaneous impulse and continuous force: these are the foundations of Newton laws. In short explanation; concept of force and mass.
Net force also known as an Unbalanced force.
On the Newtonian theory of gravity, gravitation affects anything with mass. Assuming that none of the answer choices is the only thing that exists in the universe, all of the answer choices are subject to the law of universal gravitation (hence “universal”).
Satellites, water, frogs, and stars all have mass as they are all composed of matter. Thus, all four answer choices should be circled.
