This statement can be said in middle school. Of course, it is not necessarily absolute. People who are good at math may not be good at physics, but this situation will account for a relatively small proportion.

When academic research reaches a deeper level, if mathematics is not good, physics will certainly be bad, let alone college physics. If you can't learn math, you basically don't have to learn it. The basic theories of college physics are all based on mathematics. After listing differential equations or calculus relations through physical laws (such as Newton's second law and electromagnetic induction law), the rest is mathematical problems.

Here I give an example of a high school topic, which I met in a high school exam before:

A cube with a length of L is placed on the lake. Assuming that the lake is calm, the top surface of the stone is squeezed by a force of magnitude F, so that the top surface of the stone is just parallel to the water surface. Find the work done by F on the block (block density ρ (wood) =0.6g/cm? , water density ρ (water) = 1.0g/cm? )

Obviously, if there is no force, the submerged length of the wood block is Lx, which is obtained by Archimedes' law of buoyancy.

ρ (wood) g L? = ρ (water) g L? LX, Lx=0.6L, when the force F is pressed to the depth of the block X,

There is obviously F=ρ (water) g L? (x-LX) = ρ (water) g L? (x-0.6L), so if the block presses dx distance (dx→0), then there is

Dw = f dx = ρ (water) g L? (x-0.6L) dx, so the work done by f is:

w =∫& lt； 0.6L, L>ρ (water) g L? (x-0.6l) dx, where < 0.6l and L> represent the upper and lower limits of the integral. By calculating this definite integral, the work can be calculated.

Of course, this problem can be solved by kinetic energy theorem. At this time, the change of the height of the center of gravity of the wood block should be considered. Because middle school physics is relatively simple and calculus tools have not been used, mathematics is not very important to physics.
