Example

A 36 kg object is 15 m above the ground. What is its potential energy? (PE = mgh, g = 10 m/s²)

Answer: 5400 J

RememberPotential and kinetic energy

top: most potentialbottom: most kineticPE = m × g × h (height)KE = ½ × m × v² (speed)Energy changes form butthe total stays the same.

    A 13 kg object is 10 m above the ground. What is its potential energy? (PE = mgh, g = 10 m/s²)

    13kgh = 10 mPE = m g hg = 10 m/s²

    A roller coaster is at the very top of a hill. Is its potential energy at a maximum or minimum?

    MaximumMinimum
  3. 3

    A 3 kg object is 29 m above the ground. What is its potential energy? (PE = mgh, g = 10 m/s²)

    3kgh = 29 mPE = m g hg = 10 m/s²
  4. 4

    A 14 kg object moves at 6 m/s. What is its kinetic energy? (KE = ½mv²)

    14 kgv = 6 m/sKE = ½ m v² = ?
  5. 5

    If an object's mass doubles at the same speed, what happens to its kinetic energy?

  6. 6

    A 2 kg object is 11 m above the ground. What is its potential energy? (PE = mgh, g = 10 m/s²)

    2kgh = 11 mPE = m g hg = 10 m/s²
  7. 7

    A 20 kg object moves at 12 m/s. What is its kinetic energy? (KE = ½mv²)

    20 kgv = 12 m/sKE = ½ m v² = ?
  8. 8

    An 8 kg object moves at 10 m/s. What is its kinetic energy? (KE = ½mv²)

    8 kgv = 10 m/sKE = ½ m v² = ?
  9. 9

    A 19 kg object moves at 11 m/s. What is its kinetic energy? (KE = ½mv²)

    19 kgv = 11 m/sKE = ½ m v² = ?
  10. 10

    An 18 kg object moves at 5 m/s. What is its kinetic energy? (KE = ½mv²)

    18 kgv = 5 m/sKE = ½ m v² = ?
  11. 11

    A 9 kg object is 5 m above the ground. What is its potential energy? (PE = mgh, g = 10 m/s²)

    9kgh = 5 mPE = m g hg = 10 m/s²
  12. 12

    A 6 kg object is 6 m above the ground. What is its potential energy? (PE = mgh, g = 10 m/s²)

    6kgh = 6 mPE = m g hg = 10 m/s²
