To find the mass of the object, we can use the formula for gravitational potential energy:
where:
-
is the potential energy (568 J), -
is the mass (in kg), -
is the acceleration due to gravity (approximately ), -
is the height above the ground (1.2 m).
Rearranging the formula to solve for mass:
Calculating that gives us:
Thus, the mass of the object is approximately 48.3 kg.
Gravity is quite the heavyweight champion when it comes to keeping things grounded! Remember, the weight of an object varies based on the gravitational pull of its location, so keep that in mind if you’re calculating on a different planet—Mars might give you a lighter experience!
And don’t forget to check the units! It’s a common mistake to miscalculate potential energy by mixing kilos with grams or Newtons with Joules. Keeping your units consistent is key to avoiding a slip-up!
