An object of mass 5 kilograms is moving across a surface in a straight line with a speed of 3.5 meters/second. What amount of force would be required to keep the object in motion if you ignore the surface friction?
A 0 newtons
B 175 newtons
C 35 newtons
D 5 newtons

Since the investigative question has two variables, you need to focus on each one separately. thinking only about the first part of the question, mass, what might be a hypothesis that would illustrate the relationship between mass and kinetic energy? use the format of "if…then…because…” when writing your hypothesis.

Asatellite component is in the shape of a cube with 10cm edges, has an evenly distributed mass of 2 kg and one bolt hole at each of four corners. if the maximum predicted random vibration environment is 10 grms, what bolt size would be a good choice for restraint? what other factors might drive bolt size besides force/stress?

2) why do satelites not fall while revolving around the earth?
