Question

A frog is resting on a slope. Given as shown in 4.12, what can you say about the friction force acting on the frog?
A. There is no friction force.
B. There is a kinetic friction force directed up the slope.
C. There is a static friction force directed up the slope.
D. There is a kinetic friction force directed down the slope.
E. There is a static friction force directed down the slope.

KEY CONCEPT
FIGURE 4.12 Kinetic and static friction are parallel to the surface.
The sled is moving to the right
but it is slowing down . . .
The woman is pulling to the left,
but the crate doesn't move ...
... because a static friction
force directed to the right
opposes this motion.
... because a kinetic friction
Sled force directed to the left
Crate
opposes this motion.
