Physics involves math because calculations have to be made and u use math to make calculations
Answer:
v = at + u

Explanation:
acceleration, a = constant
As we know that acceleration is the rate of change of velocity


integrate on both sides

v = at + u
Where, u is the integrating constant and here it is equal to the initial velocity
Now we know that the rate of change of displacement is called velocity


Integrate on both sides


where, xo is the integrating constant which is initial position of the particle.
Answer:
When dealing with the force of gravity between two objects, there are only two things that are important – mass, and distance. The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them.Explanation:
The answer to this is B, C, and D. hope this helped
