The Force used in an onager catapult is exerted near its axis. (The catapult has both twisted rubber at the axis and a rubber band just above it, pushing the arm near its base like a slingshot).

When we double the length of the arm of the catapult, but still use the same Force at the same point as before near the same axis, does the distance in the Torque equation change?

In an experiment we have found that the longer arm/lever makes the ball fly a longer distance, but how do we compute this into the equation? Is the force element perpendicular to the arm not related to the exact spot (distance from axis) where the force is exerted?

We also tried 3 types of balls with the same size but different mass.

How can one combine the mass of the ball used by the catapult with the calculation of the torque?

It's a bitter cold winter morning and there are thin patches of ice on your sidewalk. Although the temperature never rises above 10 °F -12 °C), the ice is gone when you return in the evening. If you had examined the surface of the ice closely enough, you would have observed water molecules

A. only leaving the solid for the gas.

B. leaving the solid for the gas much more often than they land from the gas on the solid.

C. becoming separate oxygen and hydrogen molecules and entering the gas phase.

D. leaving the solid for the gas much less often than they land from the gas on the solid.

What I'm going to ask is very confusing for me. In my Calculus book, I read;

s(t) = distance a particle travels from time '0' to 't'.

v(t) = velocity of a particle at time 't'.

a(t) = acceleration of a particle at time 't'.

My first question is; Are velocity, distance, and acceleration only the function of time?

If they are not, then in which case they are only the functions of time? Because, in the above three functions, they seem to be the function of time only.
