What types of friction occur when you ride a bike through a puddle?
Fluid Friction, & Rolling Friction.
What are two examples of friction?
Say you are driving a car or riding a motorcycle and you just remove you foot or hand from the accelerator. What will happen? After some time depending on your velocity, the vehicle will stop. Why? Consider your entire vehicle an ideal system meaning that no part provides any sort of friction. Now consider road, road is rough and will definitely provide friction. Since your vehicle's tires are rolling against the road, the road will provide friction in the direction opposite to that of your vehicle's motion. In real situations, both tire and road will contribute to the rolling friction.

Which are 5 activities that require friction?
riding a bike walking siting down riding a roller coaster sledding skiing grating food pretty much anything
What type of friction is there?
1) Static Friction: When it's hard to move an object (i.e.: moving a large refrigerator box is difficult because of the large mass pressing down and the static friction between the box and the floor)2) Sliding Friction: Tiny friction particles in between objects that slow them down (i.e.: moving a cafeteria tray in the lunchline--there's a little bit of friction between the tray and the metal bar, which causes the tray to move slowly)3) Rolling Friction: The friction between wheels (or anything rolling) and the ground. (i.e.: riding a bike. Without rolling friction, we would speed out of control. Walking would also be impossible because our feet collide with the pavement and gently roll off. With no friction, we'd be slipping and sliding everywhere! =D)
How is riding a bike gravitational energy?
Rolling down a slope.

Does rolling or sliding friction enables you to ride a bike without skidding and falling?
Sliding Friction

What forces are acting when you are riding and then thrown from your bike?
The forces acting on the bike is gravity, air resistance and friction.
What types of friction occur while you ride a bike through a puddle?
You would experience fluid friction and rolling friction, and since you are not likely to be completely submerged, air resistance.
What three forces do you exert while riding a bike?
applied, normal, and friction
What force do you have to overcome when riding a bike?
Friction - several different kinds - and inertia. If riding uphill, also gravity.

Which friction has least value option sliding friction static friction rolling friction Air friction?
i think it it rolling friction
Is the limiting friction is always less then rolling friction?
no limiting friction is not less than rolling friction
Name 2 ways that friction is helpful when riding your bike?
Friction lets the drive wheel push you forward, and allows your brakes some bite. Friction make it possible to hold on to the bars. Friction lets you steer.
