Recall the pulling a cart up a changing angle lab.
The amount of force (to an asymptote) with each trial while pulling the car up the hill at an increasing angle.
The work that was done with each trial.
Match the 'Example' to the appropriate classifciation:
vertical displacement was 4m, the horizontal force was 20N
force directly caused the displacement
there was no force to cause the dispalcement
the item sits on the shelf with 40J of Potential Energy
there was zero displacement
Work Was Done
No Work Was Done
Calculate the work done by a 30-N force (directed at a 10° angle to the vertical) to move a 1-kilogram box a horizontal distance of 400 cm across a rough floor at a constant speed of 0.8 m/s. (Make sure you show your work for partial credit!)
If you double the amount of displacement of a spring relative to its equilibrium position, then you the PEspring.
There is a ball that is 65m above the zero line that has a mass of 55kg. The ball current PEgrav =
When you quadruple the speed of an object, you its KE by a factor of .
When you reduce the speed of an object by a factor of 3, you its KE by a factor of .
