71. Are the direction of acceleration on a body and the
direction of external force acting on the body always
the same? If not, give an example. If the given state-
ment is true, how do you account for it in the fol-
lowing situation? A toy car is tied to a string and is
being pulled in a direction making an angle with the
horizontal, whereas the toy car accelerates in a hori-
zontal direction as shown in the figure.

Answer:
Not true.
Explanation:
When a body is thrown upward,force is applied by us in upward direction but acceleration due to gravity acting downward.
Answer:
yes it is possible that the direction of acceleration on a body and the external force acting on the body always the same according to newtons second law of motion the direction force is same as the direction of momentum momentum is the change of velocity ×mass in unit time but
Explanation:
mass is constant so change in velocity in unit time is called acceleration so this statement is true in the sense of toy car the direction of force along the horizontal make angle thita so acceleration along the horizontal is also same so we can say that the direction of force and acceleration is same along the horizontal
