Scale Reports Accurate Weighing of an elevator when?
Elevator is not acceleration or decelerating.
If you put twice the force (in this case the weight, in N) on the swing...it will
stretch twice as much, as long as you are within the elastic limit.
A spring that is "soft" has a smaller spring constant than one that is "firm,": True or False
Whenever the net force on an object is zero, the object:
Is in Equilibrium
Mass Vs Volume Vs Weight
Mass (in kg) is always completely independent of the local gravitational constant. Volume (in m^3) is relatively independent of gravitational constant. Weight of the object (mg -- in units of N) is likely to change when going to planets with different gravitational constants.
Mass Vs Volume Vs Weight: 2
Weight of the object (mg -- in units of N) is likely to change when going to planets with different gravitational constants.
Astronaut brought a spring scale from Earth to the Moon to take readings of lunar objects. The spring scale ____ take accurate readings on the moon.
does not because the weight of objects is different on the Moon.
While the gravitational constant changes form planet to planet (or in this case from planet to moon)...continued
Astronaut brought a spring scale from Earth to the Moon to take readings of lunarobjects. The spring scale ___take accurate readings on the moon.(2)
the spring constant is a constant that only depends on the composition of the spring and its geometry.
you notice that the bungee cord's equilibrium length is now longer than the original unstretched length...what happened?
the cord was stretched past its elastic limit
You place a watermelon in the basket of a grocery-store spring scale. The spring scale works because:
the stretch of the spring has been calibrated to standardized weights.
Measure of the springs stiffness "soft springs" = low spring constant; stretch or compress lots, distort easily "hard springs" = high spring constant; do not stretch, compress, or distory easily
