A force of 50 N moves an object 3 m in the direction of the force. How much work is done?
Which equation links pressure (p), force (F) and area (A)?
Which expression is the kinetic energy (Ek) of a moving object?
A machine has an input energy of 500 J and an efficiency of 80% (0.80). What is the useful energy output?
A constant horizontal force of 30 N moves an object at constant speed of 2 m/s. What power does the force provide?
How much gravitational potential energy is gained when 100 kg of water is pumped 10 m higher? (g = 9.8 N/kg)
A car engine does useful work of 80 kJ for every 100 kJ of fuel energy supplied. If the engine supplies 160 kJ useful energy per minute, what is the fuel energy input per minute?
Which equation gives the work done (W) by a constant force?
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)?
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 2.0 kg object is lifted vertically by 5.0 m. What is the increase in its gravitational potential energy (use g = 9.8 N/kg)?
