Frictional Force. It is a 'reactive' force, and can only respond when another Force is applied. It can SLOW a motion, or cause a change in Direction.
An engine is the usual source of thrust in an aircraft.
In Physics, "normal" force means force that's perpendicular to something, usually to a surface.In that usage, 'normal' does not mean ordinary, typical, usual, familiar, etc.
The most usual way to convert thermal energy (i.e., heat) into motion is by means of a steam engine. You boil water, the steam pushes on a piston, and the piston can then move whatever it is that you want to move.
The most usual downward force is the force of gravity; the weight of an object exerts force in a downward direction. There are also other forces which can be exerted in that direction. If you wanted to, you could fire a gun in a downward direction, in which case the explosive force of the gun is added to the force of gravity.
Any force acting in the direction opposite to that of the motion. It could be a braking force, or drag (resistance from the fluid in which the body is moving), or friction (resistance from the body along which it is moving)

For a usual man:100 For a usual woman:75
Do you mean "change"? If you're talking about "simple machines", the usual answers are direction (eg., with a pully), speed, and force.

A Change in the Morphology
Yes. When the clock runs out, the play currently in motion is allowed to complete as usual.
its bigger than usual and it has more gravitational force.
The usual litter size is 2 to 3.
Mainly kava for export, otherwise usual tropical seasonal fruit and vegetables.

The usual noun corresponding to "venerate" is "veneration".
Friction produces unnecessary heat leading to the wastage of energy.The force of friction acts in the opposite direction of motion, so friction slows down the motion of moving objects.Forest fires are caused due to the friction between tree branches.A lot of money goes into preventing friction and the usual wear and tear caused by it by using techniques like greasing and oiling.
