NLN PAX Physics Exam (Answerd) Verified Solution Displacement Distance that an object is from some starting point, and it is measured in units of length. Motion when an object is in motion, it's displacement is constantly changing. -Velocity (speed) -Acceleration Speed Is the distance traveled by an object per unit of time. - Speed equals distance traveled over time. Velocity Speed in a given direction; it therefore tells us two things about a moving object, it's speed and direction...

Inertia CORRECT ANSWER An object's tendency to resist a change in motion Force CORRECT ANSWER A push or a pull What is the unit of force? CORRECT ANSWER Newton Mass CORRECT ANSWER A measure of how much matter is in an object A measure of inertia of an object... An object with a larger mass will resist a change more. System CORRECT ANSWER A collection of particles or objects that is isolated from its surroundings. All forces within a system are called internal forces, and forc...
