Can you talk me through how to solve problems on projectiles? I always get confused

The strategy is to consider the horizontal and vertical components of the motion separately, and use the equations of motion in each direction. A few things to remember are: the vertical acceleration is alwa...

Given the Earth orbits the Sun at a distance of 1.49*10^11m with Me = 5.97*10^24kg and Msolar = 1.99*10^30, what is the gravitational force between the Earth and Sun?

Using F = Gm 1 m 2 /r^2 and substituting in the values, we get F = 3.57*10^22N.

Why does the Photoelectric Effect lead to the conclusion that classical physics cannot be all of physics?

The photoelectric effect is the emission of electrons on a charged zinc plate, when UV light is shone on it, but not low energy visible light. This phenomena is caused by the quantisation of light. Classical...

What is the difference between linearly, directly and inversely proportional relationships?

A relationship is a way of describing how one variable can affect another. If a relationship is linear, then a change in one variable will cause a change in another variable by a fixed amount. An example of ...

Give the definition simple harmonic motion and write down the defining equation for such motion stating the meaning of any symbols involved.

Simple harmonic motion is defined as a form of periodic motion in which a point or body oscillates in such a way that the acceleration of the point or body is directly proportional to its displacement from t...
