An introduction to tension. Solving for the tension(s) in a set of wires when a weight is hanging from them.
The second part to the complicated problem. We figure out the tension in the wire connecting the two masses. Then we figure our how much we need to accelerate a pie for it to safely reach a man's face.
A simple conservation of momentum problem involving an ice skater and a ball.
An example of conservation of momentum in two dimensions.
