Section 1: Force
Key Concepts
- A force is described by its strength and by the direction in which it acts.
- Unbalanced forces acting on an object result in a net force and cause a change in the object’s motion.
- Balanced forces acting on an object do not change the object’s motion.

Part 2: Simple Machines
- A machine makes work easier by changing at least one of three factors. A machine may change the amount of force you exert, the distance over which you exert your force, or the direction in which you exert your force.
- A machine’s mechanical advantage is the number of times a machine increases a force exerted on it.
- To calculate the efficiency of a machine, divide the output work by the input work and multiply the result by 100 percent.
