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:
