What is the modulus of movement of the body relative to the fixed frame of reference, if: a) the directions of movement of the body and the moving frame of reference coincide; b) the body and the moving frame of reference move in opposite directions; c) the body and the moving frame? move at right angles to each other

a) When the directions of motion of the body and the moving frame of reference coincide, then the modulus of movement of the body S, relative to the stationary frame of reference, will be the sum of the displacement of the body S1, relative to the moving frame, displacement S2 of the moving frame, relative to the stationary frame.

S = S1 + S2.

b) When the body and the moving frame of reference move in opposite directions, then the modulus of movement of the body S, relative to the stationary frame, will be the difference between the displacement of the body S1, relative to the moving frame, the movement S2 of the moving frame, relative to the stationary frame.

S = S1 – S2.

c) When the body and the moving frame of reference move at right angles to each other, then the modulus of movement of the body S, relative to the fixed frame of reference, will be determined by the formula: S = √ (S1 ^ 2 + S2 ^ 2).
