To keep a sled accelerating downhill what must the force of gravity be greater than?
To keep a sled accelerating downhill, the force of gravity must be greater than the force of friction acting against the sled. This allows gravity to overcome the frictional force and propel the sled forward.
To keep a sled accelerating downhill the force of gravity must be greater than the normal force?
A sled accelerates downhill when the force of gravity pulling it downhill is greater than the force of friction and air resistance acting against it. This difference creates a net force that causes the sled to accelerate. The normal force from the surface helps support the sled against gravity but does not impact its acceleration directly.
Is it true that a sled accelerating downhill the force of gravity must be greater than the normal force?
Yes, when a sled is accelerating downhill, the force of gravity pulling the sled downhill must be greater than the normal force acting in the opposite direction to overcome friction and any other resistive forces. This difference in force is what allows the sled to accelerate downhill.
Is it true that kinetic friction is always greater than the maximum value of static friction?
Yes, it is generally true that kinetic friction is always greater than the maximum value of static friction.
What are the 3 examples of unbalanced forces?
When a person pushes a door, creating a force greater than the friction on the hinges, causing the door to open. When a car accelerates, the engine exerts a forward force greater than the resistive forces like air resistance and friction. When a book slides off a table due to the force of gravity being stronger than the friction keeping it in place.
To keep a sled accelerating downhill what must the force of gravity be greater than?
To keep a sled accelerating downhill, the force of gravity must be greater than the force of friction acting against the sled. This allows gravity to overcome the frictional force and propel the sled forward.
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.

A sled accelerates downhill when the force of gravity pulling it downhill is greater than the force of friction and air resistance acting against it. This difference creates a net force that causes the sled to accelerate. The normal force from the surface helps support the sled against gravity but does not impact its acceleration directly.
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.
Static friction is usually greater than?
kinetic friction
What is Static friction is usually greater than?
sliding friction

What friction is greater than sliding friction?
Static friction is greater than sliding friction. Static friction occurs when an object is at rest and an external force is being applied to move it, requiring a greater force to overcome the initial resistance compared to when the object is already in motion and experiencing sliding friction.
Gravity is greater than what?
In the context of celestial bodies, gravity is greater on larger objects with more mass. For example, Earth's gravity is greater than the moon's gravity due to Earth's larger size and mass.
What if lift is not equal but is greater than gravity while flying straight?
If the lift is greater than gravity then the airplane gains altitude.
