# [S1] LESSON 44 : Physics Headstart L3 – Work, Energy, Power Updates/Debrief

[S1 Maths + Science PMCians]

What we did in 2 hours:

Following the two weeks of Maths Headstart, this week we started our Science Headstart on a Physics topic – Work and Energy.

The two types of energy that we learnt are:

1) Kinetic Energy (KE): the energy possessed by an object due to its motion. (KE = 1/2 m v^2)

2) Gravitational Potential Energy (GPE): energy possessed by an object due to its vertical height from the ground. (GPE = mgh)

Work done involves the transformation of energy from one form to another. It is the product of the force applied on an object and the distance travelled by the object in the same distance as the force. (WD = Fd)

In summary, the one important statement that you need to REMEMBER in this lesson:

Work Done = GAIN in KE + GAIN in GPE

Lastly, we had fun with Kahoot! before we ended our heatstart on Work and Energy. 🙂

Special Mention:

Next lesson we will begin our Science Headstart on a Chemistry topic – Ionic Bonding.

See you soon! 🙂
