Movement in a circle and centripetal force

Galileo - Everybody continues to move with a constant speed unless acted on by a       resultant force

From this Newton established his first law of motion.

An object that is moving in a circle is said to be accelerating, even if there is no speed change, because the velocity is constantly changing.

A net inward force is needed to provide this acceleration. This 'centripetal' force, f, always acts towards the centre…


Miss KHP

Some nice and simple notes about movement of a circle for AQA GCSE triple science.

Test yourself afterwards to see how much information you have retained. Remember, practice makes perfect!

Not sure why you inconsiderate pricks don't want to help people like me doing their GCSEs pass. Your website is ****.
