Is pulley a speed multiplier or a force multiplier?
force
Can speed be treated as force in direction and opposite speed?
Speed and force are quite different things.
How does drag work?
Drag force, or the force of air friction for a falling body, increases with speed. A falling object will reach a speed at which the force of air friction will be equal to and opposite the force of gravity. At that point, the object will no longer accelerate. It's speed will remain constant, and we call that speed (and direction) its terminal velocity.
How can you find force when given distance and speed?
You cannot. Force is mass times acceleration. You have neither.
The increase of speed is a squared relationship Three times the speed will have nine times the force of impact?
true
Which is better a machine which multiplies speed or a machine which multiplies force?
a machine which is a speed multiplier is the better one

Is a golf club a speed or a force multiplier?
AnswerA golf club is a speed multiplier
Are stairs force multipliers or speed multipliers?
Speed
Is gear a force multiplier or a speed multiplier?
Both. A small driving gear and a large driven gear is a force multiplier. Whilst a large driving gear and a small driven gear is a speed multiplier
What is the difference between a force multiplier and a speed multiplier?
A force multiplier increases the effort force and the mechanical advantage is larger than one (Which means it is easier to move a large load with a small effort). While the speed multiplier does not make the effort easier but makes the load move through a larger distance than the effort. The mechanical advantage of a speed multiplier is usually lower than 1.
What are some examples of force multiplier gears?
Philadelphia gear or Farrel gear are two brands of force multiplier gears. They consist of a driven pinion gear meshed with a larger bull gear driving a machine. The rotational force (torque) exerted on the pinion is multiplied by the difference in size of the bull gear it is driving, converting the input shaft speed into greater torque at the output shaft running at a slower speed.
What is machines mechanical advantage?
it is d ratio of the load to the effort applied to move the load if mechanical advantage>1(ie L/E >1), the machine acts as a force multiplier otherwise as a machine to gain speed mechanical advantage is abbreviated as M.A.
What is speed multiplier?
a speed multiplier is an object which moves at high speed and multiplies that to create more speed with an object it is trying to move. an example is hitting a tennis ball with a tennis raquet - you swing your arm/hand at a short distance at high speed and great effort so travels a great distance at an even higher speed. the distance the ball moves is large so the force by your arm/hand is small. hope this helps! :)speed multiplier- machine that requires a small movement of an effort to produce a large movement of a load, such as a third class lever.source: Pearson Science S.B
