Forces - GCSE Physics

This video introduces the concept of forces. Some forces, like friction, act when two objects are touching. These are called contact forces. Others, like gravity, act at a distance. These are called non-contact forces. This is one way we can categorise forces: contact and non-contact forces.

Other examples of contact forces are: tension, air resistance, water resistance, drag and the normal contact force. Other examples of non-contact forces are: the electrostatic force and magnetic force.

Forces are measured in newtons, N.

Happy New Year ! Thank you so much for all your hard work, these videos are so useful and interesting. I’ve just got my science mock results and I got an 8 in physics thanks to your amazing videos! I didn’t do so well in the other sciences which I am disappointed with, but really happy with physics so thank you !

Very clear! Thank you. Could you also make one about vector forces, how you could calculate 2 force in different directions
