Path take If he swims around the pool 4.5 times, how far has he travelled?
500m
B
500m
С
250m
100m
1
600m
D
700m
E
200m
300m
H 400m
G
300m
Now find his Displacement between the following points:
(displacement is the shortest distance from where he started and
requires a direction!)
A->
A->F
A->G
B->H
F-> A
H->A
He swims from point A -> B -> D for a chat with his friend. a)
Calculate the distance he has swam.
b) Calculate his displacement.

it would be c. predictability

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 -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [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.
