GeoGebra Animations for Physics Teachers: Beats and Interference

The following animation is ideal for physics teachers to explain the phenomenon of interference when beats are formed by the combination of  two waves which have slightly different frequencies. You can see the individual waves as well as the resultant wave. Constructive and destructive interference …

Radioactive Decay & Nuclear Physics: half-life simulator

Radioactive Decay Radioactive substances such as Uranium and Radium spontaneously disintegrate while emitting radiation in the form  of α or ß particles and γ rays. The loss of an alpha particle result in the formation of a new element,  that occupy a position on the Periodic Table, two places to the…

Iteration for A Level Maths: staircase method & cobweb method

E.g. f(x) = x² - x - 4 When the above is rearranged in the form of x = g(x), it is said to be in iterative form. x² - x - 4 = 0 x = 1 + x/4 x n+1 = 1 + x n / 4 If x n is known, x n+1 can be calculated. The initial value to trigger off the iterative process is found by looking for change in sign of…

Simple Harmonic Motion for A Level Physics: vertical motion of a spring

Upward force, T', when the stretched spring is released = k(e+x) If the resultant force is F, F = K(e+x) -mg F = ma - Newton's Second Law k(e+x) - mg = ma, where a is the acceleration (ke + kx) - mg = ma Since T = ke mg - mg + kx = ma ma = kx a = k/m x a ∝ x ω 2  = k/m T =2π √(m/k) T =2π √(m/k) Since the a…

Mechanics - A Level Applied Maths & Physics: really challenging questions

An object that falls off a tree travels 16/25 th of the height of the tree during the last second. Assuming that g = 10 m/s², find the total time taken for the fall and the height of the tree. A balloon is steadily rising at 5 m/s. After 4 seconds of its motion, a nail from the balloon falls off. Sk…
