- nichrome alloy

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?

What is the momentum of a 2 kg object moving at 15 meters per second

If the force applied to an object remains constant, is more power needed for the object to move faster ? explain
