momentum
Friction causes erosion through wind or water.
The pressure or force causing current to flow through a conductor is called voltage.
The spread of matter causing a concentration of energy.
A washer is used to spread out the force that a bolt applies to an area. This is used in order to keep the bolt from pulling through, damaging, or causing an unwanted result - while still holding as intended.
Seismic Waves.
Not much is known about dark matter, but it is believed to interact with normal matter ONLY or ALMOST EXCLUSIVELY through gravitation; its interaction through the other forces (electric and magnetic forces, the strong force, the weak force) should be inexistent, or insignificant.
the upward force of displaced fluid causing flotation is a buoyant force.
You can use matter or light to measure the force of gravity, because gravity distorts the shape of space around the gravitational body thus distorting the path that matter or light travels through that space.
The two are quite unrelated. It would be harder to find similarities than differences. More exactly, the two are only related by the fact that (as of 2013) we don't understand either -- thus the name "dark." Dark matter is the type of matter that exists throughout our Universe, which interacts with baryonic matter (ie, the stuff we understand) only through gravity. This stuff (whatever it happens to be) warps space and prevents galaxies from flying apart as they spin; but does not interact via the electromagnetic force, the strong force, or the weak force. Its mass density in our Universe, as best we can tell, is about six times greater than that of bayronic matter. Dark energy is whatever is causing the space within our Universe to increase the rate of expansion. Gravity SHOULD be slowing down that expansion over billions of years, but SOMETHING is causing the rate to go higher. What is causing this? -- we have no idea!!
When a force (no matter how large it may be) is applied to any object without a distance being moved,it cannot be workdone because,workdone = force x distance.
What is the result of a force distributed over an area?
Acceleration is the result of unbalanced force.
