The Margin of Error That the Equipment Allows - Essay Example

The time taken for the projectile of the ball to complete a distance is not taken and therefore, we cannot use Newton’s to calculate the initial velocity.
Task 3

The method is easier to manipulate and only easier measurements are required.
According to the law of energy conservation, the energy content of a body cannot be lost. In this case, the energy content at the beginning of the projectile motion will be the same at all stages. This means that the total kinetic energy at the beginning will be converted to potential energy at the highest point.
That is:
½ mV2 = mgh
It is evident from the equation that only Velocity (V) requires to be measured using at least sophisticated equipment. All the other parameters can be measured readily in the laboratory. Read More
