If a 50 kg student is standing on the edge of a cliff.   a.  find the student’s gravitational potential energy if the cliff is 40 m high. b. find the student’s gravitational potential energy if the cliff is 80m high

Orque can be calculated by multiplying the force (n) applied at 90∘ to the lever arm at a distance (m) from the pivot point (point of rotation), the compound si unit for the torque is n⋅m. if the force (at 90∘ to the lever arm) applied is 15 n and it is applied at 2.0 m from the pivot point (point of rotation), what is the torque on the lever?
