Energy stores

This activity uses the Fametoys Bridger Raspberry Pi Zero W controlled train system to revise energy stores and calculating kinetic energy of a moving object.

Method

**Step 1**

Build a suitable track on a bench or on the classroom floor. You will need to know the length of the track. A very easy way of measuring the length is to use a piece of string to lay around the track and then measure it with a ruler.

**Step 2**

Measure the mass of the train on a top balance and convert to kg

**Step 3**

Power on the Raspberry Pi Zero W and establish a connection with a computer running VNC.

**Step 4**

Start the train moving at a constant forwards speed and time how long it takes to go round the track five times. Divide this time by 5 to get an average speed.

**Step 5**

Calculate the kinetic energy

Repeat steps 4 and 5 increasing the speed and calculate new kinetic energy values

**Step 6**
