Question

Fill in the blanks with missing words:

The force of friction always acts in a direction ________ to that in which motion is desired.

Answer 1

1. Friction force always act in opposite direction to motion.
2. friction force It is always equal to the applied force in the static condition in the opposite direction which prevents it to move till the limiting value is reached. if the applied force changes friction also changes accordingly.
3. It leads to a decrease in the velocity of an object.

Hence, the force of friction always acts in a direction opposite to that in which motion is desired.
