The standard unit for force, the Newton, is equivalent to which of the following

Question

The standard unit for force, the Newton, is equivalent to which of the following kg m / s kg m / s^2 kg m^2 / s^2 kg m^2 / s^3 The standard unit for energy, the Joule, is equivalent to which of the following kgm / s kgm / s^2 kgm^2 / s^2 kgm^2 / s^3 In the diagram shown to thejight, which of the forces could be a normal force? In the diagram shown to the right, which of the forces could be the weight? For a system containing both conservative and non-conservative forces, if conservative work is positive, then ... the total mechanical energy will remain the same the total mechanical energy will increase the total mechanical energy will decrease it depends on what the conservative forces are

Explanation / Answer

1) (b)

F=ma = Kg m/s2

2) (c)

energy = mgh =Kg m2/s2

3)

normal force = C

weight =B

4) (a)
