or work to be done on an object, the object must move some distance as a result of a force. A simple machine that might be thought of as an inclined plane that moves is a Wedge One example of a compound machine is a Bicycle The ideal mechanical advantage for an inclined plane is equal to the length of the incline divided by the height of the incline How can a hockey stick be considered a machine? It multiplies distance Power is measured in units called Wa...

NLN PAX Science: Physics(Answered) Complete Solution aim of physics to understand the physical laws and principles that influence every aspect of daily life displacement of an object the distance that an object is from some starting point, and is measured in units of length How does displacement change when an object is in motion? it is constantly changing How is motion described? by displacement, velocity (speed) and acceleration speed distance traveled by an object per unit of time ...

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...
