Physical Science Formula Sheet
|Formula |Description |Example |
|s= d/t |Speed = distance / time |10 m / s |
|v=d/t with a direction |Velocity = distance / time with a direction. |10 m / s north |
| | | |
|( |Greek letter “delta”; change in | |
|( |Greek letter “sigma”; Sum of | |
|a= (v / (t |Acceleration = change in velocity / change in |8 m/s 2 |
| |time | |
|g |Acceleration due to gravity |9.8 m/s2 |
|F = ma |Force = mass x acceleration |45 N (Newtons) |
|(Fnet = 0 |Equilibrium Rule = sum of the net force is | |
| |equal to zero. | |
|W = F x d |Work = Force x distance |37 J (Joules) |
|P = W / t |Power = Work / time |60 w (watts) |
|PE = mgh |Potential Energy = mass x acceleration due to |45 J |
| |gravity x height | |
|KE = ½ m x v2 |Kinetic Energy = ½ mass x velocity squared. |100 J |
|Work = (KE |Work = change in kinetic energy | J = J |
