Which of the following formulas is the correct equation for the law of Universal gravitation?
F=d2GM1M2
F=mg
F=m1m2Gd2
F= F=d2KQ1Q2
Which 2 answers provide the best definition of the value 'k'?
k is the stiffness coefficient
k is the spring constant
k is the specific spring number
k is the kinetic energy needed to stretch the spring
Which of the following best describes the relationship shown in the graph
The greater the force applied to the bungee, the greater the extension
The greater the force applied to the bungee in Newtons, the greater the extension in metres
The less force applied to the bungee, the less it extends
The less force applied to the bungee in Newtons, the less it extends in metres
Select a logical prediction for the investigation.
As the force applied to the spring increases, the extension of the spring will decrease.
As the force applied to the spring increases, the extension of the spring will stay the same
As the force applied to the spring increases, the extension of the spring will also increase.
For this spring, as the force increases, the extension increases proportionally. What would you expect to happen to the extension if the force was doubled?
The extension would stay the same.
The extension would double
The extension would halve

The energy an object has due to its motion.
The energy an object has due to its chemical composition.
The energy as object has due to its atomic structure.
