Velocity is a vector quantity so takes both magnitude and direction into account. Speed is a scalar so only takes magnitude into account. They both have units of meters per second.

To begin with, we need to draw a graph with all of the forces acting on a body.

From that, we can see that the net force Fnet = Fg - Fc , where Fg is gravitational force and Fc is centripetal ...

There are 3 forms of energy during a bungee jump, kinetic (KE = 0.5mv^2), gravitational potential (GPE = mgh) and elastic potential (EPE = 0.5kx^2). Energy is conserved throughout, and it's assumed none i...

• The resonance of a system occurs when the driving force is equal to the natural frequency. - This occurs at a certain specific frequency. - For example: someone being pushed on a swing. - (Diagram o...

For six mark questions, it is important to remember that your quality of written communication will be assessed. This basically means that you're spelling, punctuation, use of terminology and how you form...
