Have you ever noticed that objects have a tendency to resist changes in motion and just continue what they are doing? This is called (4)_ . All objects follow the same rule about changing motion - an object in motion stays in motion unless acted upon by an unbalanced force - or (5)_ _. When we talk about (6)_ , or a push or a pull on an object, we tend to talk a lot about one force in particular. (7)- is the downward pull of the Earth on objects. If you study the science of movement then vo u are

8. The below table summarizes the measured tension force (N) as a function of mass (kg), for a mass that is attached to a string and set to rotate in a uniform circular motion (with constant speed & constant radius) on a horizontal frictionless surface. Using an excel graph of F vs. m, the measured acceleration (m/s2) of the motion is: FT (kg) (N) m 0.05 1.27 0.15 3.64 0.25 6.13 0.35 8.56 0.45 11.05 O 48.96 12 24
