Three mountain climbers set out to climb a mountain from the same altitude and all arrive at the same location at the top. mountain climber a took a long gradual slope to the top, b went a steeper but shorter path, and c tackled the sheer straight side to the top. assume all three climbers have the same mass. which climber gained the greatest potential energy? a. ab. bc. cd. all did the same amount of work

When you turn on a battery-operated device, an electrical circuit is

Mass (kg) force (n) 5 25 10 50 15 75 20 100 a student was trying to find the relationship between mass and force. he placed four different masses on a table and pulled them using a spring scale. the table shows the different masses used in the experiment and the force required to pull each mass. the student concluded that more force was required to pull heavier objects. what comment would you make regarding his conclusion? a) no clear relation can be observed between mass and force from the data. b) there is a direct proportion between the mass and force listed in the table. c) gravity should have been taken into account while performing the experiment. d) there is an inverse proportion between the mass and force listed in the table.

As a pendulum bob swings back and forth several times, the maximum height it reaches becomes less and less. this is because more and more of the pendulum bob's energy is being transformed into a. heat energy b. kinetic energy c. potential energy d. kinetic energy and potential energy
