39 Questionable Assumptions in Modern Physics
... • It depends on the definition of matter. • To exert its influence elsewhere, matter must possess ‘fields’. • If an element’s field is inseparable from it (permanently attached), then it is actually present throughout all space. • Then all forces are ‘local contact forces’. • Energy density: the inf ...

Free Fall - Cobb Learning
... • Consider an apple falling from a tree. We know that it starts at rest and gains speed as it falls, or accelerates. • Gravity causes the apple to accelerate downward and is said to be in free fall. Free fall: when an object is only affected by gravity – SI unit: m/s2 ( for acceleration due to gravi ...

Chapter 5 Solutions
... Since the rollers on the ramp used by David were frictionless, he did not do any work overcoming nonconservative forces as he slid the block up the ramp. Neglecting any change in kinetic energy of the block (either because the speed was constant or was essentially zero during the lifting process), t ...
