1. Static friction 2. Sliding friction 3. Rolling friction 4. Fluid friction.

Front

What occurs when two forces act in opposite directions?

Back

The forces cancel each other out or result in a net force.

Front

What is net force?

Back

The overall force acting on an object when all the individual forces are combined.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.
