First recall the suvat equation: v^2=u^2+2as.
It is always handy to draw a diagram in physics to illustrate the problem.
Next, using u=5, a=10, s = 10, solve for v in the suvat equation, arrivi...

Before we can look at the evidence we need to look at the observations from the experiment. During the session we will go through the experiment and then the observations to deduce the atom theory - and h...

8.82 m. The 'range' means the distance along the positive x axis travelled by the projectile during its flight. First calculate the time elapsed over the flight using the SUVAT equation y = usin(θ)t - 0.5...

p = 17.9 kgm/s. p = mv. v = d/t. p = md/t. p = (5 x 50)/14

The Big Bang is the leading theory on the creation of the universe. It states that all mass and energy were concentrated at a single point before a large explosion occurred, signalling the start of time. ...
