To keep a sled accelerating downhill the force of gravity must be greater than the normal force?
"friction"
A monkey hangs stationary at the end of a vertical vine. What two forces act on the monkey?
Gravity and friction. If both forces are equal, or if the friction is greater than gravity, the monkey remains on the vine. However, if gravity overcomes the force of friction, the monkey slides down the vine. none!
Is it true that a sled accelerating downhill the force of gravity must be greater than the normal force?
Not at all. The force of gravity must be greater than the friction force, but if the sled is on any kind of slope, then it doesn't matter what the normal force is.
Why sliding friction greater than rolling friction and if the area of contact is same?
The FORCE of Friction is INDEPENDENT of Surface Area. Only the 'Coefficient of Friction', and the Force between the two Surfaces. Sliding Friction is greater than Rolling Friction ONLY if the Coefficient of Friction is GREATER for the Sliding Surfaces.
What does a coefficient of friction of 1.0 or greater mean?
It means that the maximum force of friction is greater than the weight of the object.

What makes motion?
Motion is created by an oppsing force that is greater than the rest of the common forces such as gravity, the normal force, friction and drag.
What is Static friction is usually greater than?
sliding friction
Static friction is usually greater than?
kinetic friction

Is the force needed to overcome kinetic friction greater than static friction?
No, it CAN'T be greater, and it is usually smaller.
Is the force of friction on a raindrop greater than less than or equal to the force of gravity?
less than.add. Indeed, raindrops seldom exceed about 10mm diameter, for larger sizes are broken up by the velocity of their passage - in other words by skin friction.
Why is friction greatest when an object is stationary?
Because the frictional force must be greater than forces that would cause the object to move. Example: a car parked on a slope does not move despite the force of gravity acting to pull it down the hill. Why? Because the frictional forces are greater than the forces of gravity.
Is gravity stronger than friction?
yes it is, because for instance if someone was on a slide and they were not moving gravity would help them to move but friction will not help them move so gravity is stronger
