Question

Jacob Grena raises a spoon 0.210 m above a table . If the spoon and its contents have a mass of 30.0 g, what is the gravitational potential energy associated with the spoon at that height relative to the table's surface?

Answer 1

Step-by-step explanation:

The spoon is raised so it gains Gravitational potential energy. Formula to find Gravitational potential energy;

Gravitational potential energy = mass × Gravitational field strength × height of the body from the surface (table in this scenario)

In symbols; E = m×g×h

Substitute values:

m = 30g = 0.03kg (don't forget to convert grams to kg)

g = 10N/kg

h = 0.210 m

So it's;

0.03kg × 10N/kg × 0.210m = 0.063 Joules

SI Unit of energy is joules
