PLEASE HELP 100 POINTS If the simple machine reduces the amount of force, what must be increased? (Think of using an inclined plane)

the size of the simple machine

the speed of the input force

the work the simple machine performs

the distance over which the force is applied

Answer;
A. the distance that the force move
Explanation;
Simple machines function to make work easier by reducing human effort. These machines may increase the strength of the force, or increase the distance over which the force applied or even change the direction in which the force is applied.
Therefore, when these simple machine reduce strength of a force then the distance over which the force is applied or moves should be increased. Examples of machines that makes work easier by increasing the distance over which the force is applied include, hammers and leaf rakes.

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

$f\alpha \frac{dp}{dt}$

⇒ $f= k \frac{dp}{dt}$

here k is the proportionality constant whose value is 1.

$f=\frac{dp}{dt}$

$f= \frac{d[mv]}{dt}$

$f= m\frac{dv}{dt} +v\frac{dm}{dt}$

$f=ma+v\frac{dm}{dt}$ [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.
