- PHYSICS EQUATIONS
- Workdone = Force x distance
- W (J) = F (N) x s (m)
- Weight = mass x gravitational field strength
- W (N) = m (kg) x g (N/kg)
- g= 9.8 N/kg
- W (N) = m (kg) x g (N/kg)
- Change in objects gravitational potential energy store= mass x gravitational field strength x change in height
- /_\ Ep (J)= m (kg) x g (N/kg) x /_\ h (m)
- Kinetic energy store = 1/2 x mass x velocity²
- Ek (J) = 1/2 x m (kg) x v² (m/s)
- Hooke's Law Force = spring constant x extension
- F(N) = k(N/m) x e(m)
- Elastic potential energy store= 1/2 x spring constant x extension²
- Ee (J) = 1/2 x k (N/m) x e² (m)
- efficiency= useful energy (J) / total energy (J) (x100 (%))
- Power= energy / time
