Physics 10-27-23 Friction & Normal Force & Forces at an Angle

PHYSICS: Why don’t things that are moving just keep moving? And then what happens to your applied force when you pull or push something at an angle?

Super important to remember – it’s not forces, but net forces that produce acceleration. So this means there are a couple of different ways to look at Fnet – a whole made up of parts and something that produces accelerations. Good stuff!

Another good reminder – you can find Ff a couple of different ways – it’ll be part of a net force equation and can be found from the coefficient of friction equation. If and ONLY if your object is moving at a constant velocity, Ff will equal Fa. Fn is only sometimes equal to Fw. If your object is pulled at any angle (or pushed), Fn will be a part of Fnet in the vertical direction.

Whew! 🙂
