Is the motion of a mass on a spring when it is subject to the linear elastic restoring force given by Hooke's Law. The motion is sinusoidal in time and demonstrates a single resonant frequency. There are ...

We know that both balls have the same kinetic energy, so we can write E_ka = E_kb We also know that kinetic energy is given by the equation E_k = 1/2 (mv²) and mom...

A force is any influence that causes an object to undergo a specific change. Resulting unbalanced forces can cause changes in speed, shape or direction, whereas equal or balanced forces result in an equil...

Hydrostatic pressure originates from the weight of the liquid. At a certain point in the liquid, the hydrostatic pressure is going to be equal to the weight of the liquid above the examined point.  So in ...

This question asks students to recall the equation Work done = Force x Distance. 

In this question, students must multiply 200 by 5, with the answer being 1000 Joules. 

It is important that ...
