If there was no friction, which way would the yoyo rotate? And, therefore, which way would the contact point of the yoyo tend to slip on the surface of the incline? Which way must friction act to prevent such slipping?dahoom102 said:
Take moments about the centre of the yoyo. What does that tell you about F and fs?dahoom102 said:
The direction of friction in a yoyo rolling on an inclined plane is opposite to the direction of motion of the yoyo. This means that the frictional force acts in the direction opposite to the movement of the yoyo, trying to slow it down.
This is due to the nature of friction, which always acts to oppose the relative motion between two surfaces. In this case, the yoyo is rolling down the inclined plane, so the frictional force acts in the opposite direction to try and prevent this motion.
Yes, the direction of the inclined plane does affect the direction of friction. If the inclined plane is angled downwards, the frictional force will act upwards, while if the inclined plane is angled upwards, the frictional force will act downwards.
The mass of the yoyo does not directly affect the direction of friction. However, a heavier yoyo will experience a greater force of friction compared to a lighter yoyo, as the weight of the yoyo will increase the normal force between the yoyo and the inclined plane.
Yes, the direction of friction can be changed by altering the direction of motion of the yoyo. If the yoyo is rolling up the inclined plane, the direction of friction will be reversed and act in the same direction as the motion of the yoyo. Additionally, changing the surface materials of the yoyo and the inclined plane can also affect the direction of friction.
