Which of these frictions is the least in magnitude?a)static frictionb)...
The answer is option C because when you roll you push you self and there would also be less magnitude because only some of your body parts would touch the ground to cause a small amount of fiction.
please upvote to me and my answer and also start following me!!!!!

Rolling Friction
Friction is a force that opposes the motion of an object when it comes into contact with another object. There are different types of friction, such as static friction, sliding friction, and rolling friction.
Static Friction:
- Static friction is the friction that prevents an object from moving when a force is applied to it.
- It is the force that must be overcome to start an object in motion.
Sliding Friction:
- Sliding friction occurs when two surfaces slide against each other.
- It is typically greater in magnitude than static friction.
Rolling Friction:
- Rolling friction is the friction experienced by a rolling object, such as a wheel or a ball.
- It is the least in magnitude among the three types of friction.
- Rolling friction is typically lower than static and sliding friction because the rolling motion involves less resistance between the surfaces in contact.
Conclusion:
- Among static friction, sliding friction, and rolling friction, rolling friction is the least in magnitude.
- This is because rolling friction involves less resistance and allows for smoother motion compared to the other types of friction.
