Physics 1603 Exam Chapter 2 Review Questions and Answers [Level A+] 2023

Uniform motion -Motion where equal displacements occur during successive equal time intervals. -Constant acceleration -Acceleration that does not change over time. -Instantaneous acceleration -The acceleration of an object at a particular instant of time. -Acceleration due to gravity -The acceleration of an object in free fall resulting from Earth's gravity. -Contact force -A force exerted on an object only when touching it. -Long-range force -A force that acts on an object without touching it. -Inertia -The tendency of an object either at rest or moving at a constant speed to resist changing velocity. -Newton's 1st Law -If a system has no net force on it, then its velocity will not change. -Newton's 2nd Law -Acceleration of an object equals the net force on that object divided by its mass. -Static friction force -The force that opposes the start of relative motion between the two surfaces in contact. -Kinetic friction force -The force that opposes relative motion between surfaces in contact. -Newton's 3rd Law -All forces come in pairs that are equal in magnitude and opposite in direction. -Period -In any periodic motion, the time needed to repeat one complete cycle of motion. -Amplitude -The maximum distance an object moves from equilibrium in any periodic motion.
