Question

Calculate the missing term. Take g as 10m/s2
m = 1000g,  h = 10m,  GPE =? (Take g = 10 m/s2)

  1. 1000J
  2. 1000KJ
  3. 100J
  4. 100KJ

hintHint:

When the m is 1 kg and h is 10 m, the GPE will be 100 J.

The correct answer is: 100J


    • The gravitational potential energy can be calculated as GPE=mgh.
    • When the m is 1000g, and h is 10m, the formula can be applied by using the gravity value.
    • m= 1000 g= 1 Kg
    h=  10 m
    GPE=1x 10x 10=100 J.

    A roller coaster is at the top of a 72 m hill and weighs 966 N. What is its gravitational potential energy?

    The energy that an object has or acquires when its position changes due to being in a gravitational field are known as gravitational potential energy. Gravitational potential energy can be defined as energy that has a connection to gravitational force or gravity.
    Gravitational potential is the effort required to move a unit test mass from infinity into the source mass's gravitational field. Both are held above the table, with one at the table. We can now state that the pencil that is higher than the table will have more gravitational potential energy.
    ¶The formula for Gravitational Potential Energy
    ⇒ GPE = m⋅g⋅h
    where
    m represents the mass in kilograms.
    Gravitational acceleration, or g (9.8 on Earth)
    The measurement of h above the ground is in meters.
