Physics is known for its equations and calculations for the forces acting on an object that travels in a

straight line. However, there is also a force that causes objects to move in a circular motion, such as the movement of a simple pendulum that rotates

360 degrees about an axis. What is this force that is also the subject of the equation F = (mv^2)/r?

a) Electromagnetic force

b) Centripetal force

c) Inertial force

d) Quantum force

Ignoring the medium through which waves travel, the speed of a wave (v) is related to two things.

Firstly, it is related to its wavelength which is measured in metres and secondly it is related to

how many waves pass a certain yet arbitrary point per second. What physical phenomenon is

the second factor describing?

a) Frequency

b) Multiplicity

c) Capacitance

d) Conductance

Gravity is an intriguing phenomenon and it is one which we don't yet truly understand, however, the little we do know started with the work of Isaac Newton and has developed ever since. There is a specific type of energy which is related to the acceleration caused

due to gravity and this is gravitational potential energy (GPE). What is the equation which represents

GPE?

a) GPE = mgh

b) GPE = VgP

c) GPE = mgv

d) GPE = IgP
