What is the force that keeps you from sliding off a sled when it starts moving?
Friction is the force that keeps you from sliding off a sled when it starts moving. When you sit on a sled, the friction between the sled and your clothing provides the necessary grip to keep you in place as the sled accelerates.
What is air resistance that slows down a sled?
Air resistance is a force that opposes the motion of an object moving through the air. When a sled is moving through the air, the air molecules collide with the sled, creating friction and slowing it down. This force becomes more prominent as the speed of the sled increases.
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 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.
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.
