# AP Physics with Hansenator - Forces in 1 Dimension

## Forces in 1-Dimension

###### Example 1

A 24-kg box is pushed with a force of 24 Newtons. (a) What is the acceleration of the box? (b) If starts from rest, how far does it go in 4 seconds?

- Fg and FN cancel out. Unless there is friction we never use the vertical forces because it cancels. Would the box fall through the ground? No!

###### Example 2

A 48-kg lawn mower has a handle that makes a 30 degree angle with the ground. If it is pushed with a force of 50 N, what is the acceleration?

- The only force that matters is the force in the x-directions, since there is no friction. There for we use Basic Trig.
- When drawing a free body diagram it should look like this, but simpler. Notice we break up the vector into components.

###### Example 3

Derive the acceleration of this system:

bleujay (71)7 years agoThank you for posting @hansenator.

Always appreciate it when you bring your maths knowledge to Steemit.

Very well designed lay-out as well.

All the best. to you and yours. Cheers.

hansenator (57)7 years agoThanks again bleujay! As always, appreciated and more to come. Investment club is flourishing and engineering club is beginning! Documentation to be sure starting Tuesday!

clumsysilverdad (64)7 years agoMay the "Force" be with you !

hansenator (57)7 years agoHaha. I love Star Wars, but Stargate is my favorite! Thanks silverdad!
