In order to find the velocity, we need to know the distance covered by the ball in a known length of time. We are given the distance, 5.0 m, therefore we need to compute the time of flight of the ball. Th...

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...
