Force and Motion: Tension, Spring and Resisting Forces

Why is pancake syrup an example of a resistive force?
Some forces are called contact forces because they require objects to touch. One is tension force, found in stretched wires. Another is the force found in a spring. And last are resistive forces: friction, viscosity and drag. Find out more about contact forces.

Science Trek
Science Trek is a place where parents, kids, and educators can watch short, educational videos on a variety of science topics. Every Monday Science Trek releases a new video that introduces children to math, science, technology, engineering, and math (STEM) career potentials in a fun, informative way.[MUSIC] Joan Cartan-Hansen, Host: To get motion, you need a force.
There are different types of contact forces.
Contact forces are forces that act on an object when they touch each other.
There is tension force.
This is a force applied to a wire or cable that's attached to opposing walls or other objects.
That tension is the force that pulls equally in both directions.
Then there is spring force.
It's the force found in a, well, a spring.
Depending on whether the spring is compressed or expanded, it can be pushed or pulled to create a force.
Next is resisting force.
This force acts in an opposing direction to the body's motion.
Friction, viscosity and drag are all resistive forces.
Friction is the force caused when two surfaces slide against each other.
Drag is the force that pushes back on a plane or a ship as it travels forward.
And viscosity has to do with how thick a fluid is.
Syrup has a higher viscosity than water and tastes better on pancakes.
