A force of 10 N is applied perpendicular to a lever at a distance of 0.50 m from the pivot. What is the moment?
A spring with constant 80 N/m is stretched 0.20 m. What speed would a 0.50 kg mass have if all the spring energy converted to kinetic energy (ignore losses)?
Which expression is the kinetic energy (Ek) of a moving object?
Which formula defines efficiency (as a decimal)?
A worker does 150 J of work against friction by pushing a box with a force of 30 N. What distance did the box move?
A 2.0 kg object falling through height 3.0 m gains speed. Which energy store decreases as it falls?
Which action will reduce the rate at which thermal energy is lost from a hot cup?
