If this did not exist, a table you push would keep going forever. Your energy is expressed back to you.
Because the gravitational constant is not same as on earth
Given: Mass m = 0.50 Kg; Force = Weight = mg F = (0.50 Kg)(9.8 m/s²)
F = 4.9 N
Displacement x = 3.0 cm convert to meter x = 0.03 m
Required: Spring constant k = "
Formula: F = kx
k = F/x
k = 4.9 N/0.03 m
k = 163.33 N/m
Answer:
Electricity is measured in units of power called Watts,
