This causes a force to expand the object.

And finally you have possible solid objects that are sliding against the can on the inside, causing a frictional force.

This variance also causes a force in water particles as they attract by the molecular laws of attractions.

"Hydrodynamic" refers to the motion of water against an object that causes a force to be exerted upon it.

The resulting change in momentum (impulse) causes a force on the turbine blades.

They work by the electrical currents generated by motion causing a restoring force.

The explanation given is "Newton's second law states that a larger mass causes a larger force."

In the field picture, we imagine that the field generated by one particle caused a force on the other.

This causes an electromagnetic force that moves the liquid.

This can cause a net force on the object in the direction normal to the side with lower local pressure.
