Forces in Two Dimensons!

Force

Force- A push or pull on an object/ F=ma

Types of Force- Tension, Compression, Gravity, Friction, Normal

Equation for Force- F=ma

Examples- If you have a 86 kilogram corpse, how much force does it take to drag it at a speed of 10 meters per second?
  • Draw a picture of the corpse.
  • Write out the information you know.
  • Force = mass x acceleration --------> F = (86) x (10)
  • Boom shakalaka the anwser is 860 newtons



Net Force

Net Force- The total of force actiing upon the object.

Parallel Forces- If the forces are in the same direction, then simply add then together.

Example- If you and your pet jellyfish are pulling your Lamborghini out of the first circle of hell, an Dr Manhattan stops by and freezes time, what is the net force of You and your jelly fish pulling the exotic car. You weigh 150 kilograms and your jellyfish weigh 30 kilograms. The car weighs 1569 kilograms.

Complete Opposite Forces- When two forces pull in the complete opposite directions (180 degrees) the net force is the greatest amount minus the least. If they are the same amount then the net force zero.
