Ok firstly you can measure the speed of your goped, then when you get used to using the equation then you can find the acceleration, the energy your goped can propel you at.

Ø       The first equation is S= V * t

Ø       That means distance travelled = speed * time taken

Ø      Or

Ø       Speed = distance travelled / time

Ø      Or

Ø       Time = distance / time

So the first example, A goped just done a speedway that was 65 metres long and was completed in 15 seconds.

So

V =? (This is what we are going to find out)

S = 65metres

t = 15Seconds

V= S/t

V= 65/15

V= 4.3 ms^-1 (that is 4.3 metres per second)

Ok so we have just found the speed that, that particular goped can go nearly 4 metres per second!!!

Likewise if you know the weight lets say for talking sake its 20kg and then we find the acceleration, and then you can find the Unbalanced force on the Goped.

V= 4.3

U= (initial speed) 0

T= (found before) 15 seconds

A= this is the acceleration

Ø       A=v-u/t

A=4.30-0/15

A=4.3/15

A= 0.3 ms-2

Ø       Force = mass * acceleration

Force = 20 * 03

Force = 5.8 N (Newton’s)

Now that’s all but you can find the energy the Goped is acted by

Kinetic energy = half of m * v squared

Ø       Ek = 0.5m*v²
