As a roller coaster enters a loop and heads toward the top of the loop, the kinetic energy of the coaster does this.
What is decreases?
300
Gravity is this type of force.
What is conservative?
300
A rope pulls a block of wood at an angle of 25.0 degrees above the horiztonal. The force maintained in the rope is 14.0 N. It travels a distance of 16.0 m along the surface. This is the amount of work done.
What is 203 J?
300
This is the kinetic energy of a ball that weighs .5 g and is thrown at 10 m/s.
What is 25 J?
400
The work done by this type of force depends on the path taken by the object.
What is non-conservative?
400
A 4.25 kg ball is launched from the ground to a height of 29.0 meters above the Earth. This is the amount of work done by gravity.
What is -1210 J?
500
This is the formula for work (assuming the Force is in the same direction as the displacement).
What is Work = Force * Displacement
