The two kinds of unbalanced forces are:
- Net Force: Is the vector sum of all forces acting (pushing or pulling) on an object.
- Resultant Force: is a force that alone produces the same acceleration as all those forces.
To effects that unbalanced forces have on objects are:
- Can make an object move or stop.
- Can speed up or slow down an object.
Here are some examples:
- When falling out of a plane when sky diving, this is making you move faster. Then when you are using a parachute, you are slowing down.
- A man uses force to roll down an object from the top of a hill.
The retina of the human eye is made up of light sensitive
neurons which are arranged in three layers. The first layer consists of rods
and cones. The RODS are responsible for seeing black and white during relatively
low-light conditions. While the cones are responsible for color vision.
