According to Aristotle, natural motion was thought to be - -either straight up or straight down -According to Aristotle, violent motion was - -imposed motion - the result of forces that pushed or pulled. -example of violent motion - -objects in natural resting places could not be moved by themselves, they had to be pushed or pulled -if an object was moving "against its nature" then - -a force of some kind was responsible -if there were no force there would be - -no motion (except f...

Mark and David are loading identical cement blocks onto David's pickup truck. Mark lifts his block straight up from the ground to the truck, whereas David slides his block up a ramp on massless, frictionless rollers. Which statement is true? - -Mark and David do the same amount of work -Question Part Points Submissions Used If the speed of a particle is doubled, what happens to its kinetic energy? - -It becomes four times larger. -If the net work done on a particle is zero, which of th...

Which of the following statements is true - -an astronaut's mass is the same on the International Space Station as it is on earth -a truck loaded with sand accelerates down along a highway. the driving force on the truck remains constant. what happens to the acceleration of the truck as its trailer leaks sand at a constant rate through a hole in its bottom? - -it inc at a steady rate -If an object is in equilibrium, which of the following statements is not true? - -The object must be at r...

A ball is thrown straight up. At what point does the ball have the most energy? - -Everywhere; the energy of the ball is the same at all points. -A man pushes a block up an incline at a constant speed. As the block moves up the incline - -its potential energy increases and its kinetic energy remains the same. -You push very hard on a heavy desk, trying to move it. You do work on the desk - -only if it starts moving -When the speed of your car is doubled, by what factor does its kinetic ...
