Why is it harder to get an object to start moving then it is to keep the object moving?
It is harder to get an object to start moving because overcoming static friction requires more force than maintaining its motion due to kinetic friction. Static friction is stronger initially but once the object is in motion, it requires less force to keep it moving due to kinetic friction being lower.
Why coefficient of friction is less than static friction?
The coefficient of static friction is higher than the coefficient of kinetic (or sliding) friction because it takes more force to overcome the initial static friction and start an object moving than to keep it moving once it is already in motion. Static friction is present when an object is at rest, while kinetic friction occurs when an object is moving.
What happens to the magnitude of fluid friction as Speed increases?
As speed increases, the magnitude of fluid friction also increases. This is because at higher speeds, there is more interaction between the moving object and the fluid, resulting in greater resistance and friction.
What type of friction has the most friction?
Static friction typically has more friction than kinetic friction. Static friction occurs when an object is not moving, and the friction force is at its maximum to prevent the object from moving. Once the object overcomes static friction and starts moving, the friction force decreases to kinetic friction.
Effects of friction on moving objects?
Friction opposes the motion of an object, causing it to slow down. It generates heat, which can lead to wear and tear on the object's surface. Increased friction can also reduce the efficiency of moving parts, requiring more energy to overcome.

Is friction and static the same?
Limiting friction is the case of static friction where an object is right on the edge of moving, any more force applied to the object will cause it to move. Limiting friction is the largest value that the static friction can take

What happens when an object moves on a smooth surface?
The general tendency is that there is less friction on a smooth surface. The object will eventually slow down (if there are no forces to keep it moving), but the rate of slowing down will be less than on surfaces that provide more friction.
Effect of speed on the force of friction?
Friction is independent of speed once an object is moving since faster does not mean more friction.
What happens to the magnitude of fluid friction as Speed increases?
As speed increases, the magnitude of fluid friction also increases. This is because at higher speeds, there is more interaction between the moving object and the fluid, resulting in greater resistance and friction.
Why the mass of an object has an effect on speed when moving on a road?
because the more heavy it is, the more friction it has on a road. the friction slows it down.

What role does friction play when moving a heavy object?
It can make moving heavy objects easier for example sliding friction you can slide it or rolling friction you can roll the object across some kind of round cylinders or even fluid friction with water running under the object can make it easier.
Why a horse has to apply more force to start a Tonga than to keep is moving?
Because of friction. Every object has 2 friction coefficient values (called Mu and with its own symbol) - one stationary, and the other while the object is moving. It always takes more force (N) to move an object from a stand-still then it does to keep the same object moving.
What is friction affected by?
Weight and surface affect friction. The more mass an object has more friction that will occur ex:/ It would be harder to slide an elephant across a floor than a hockey puck. This is because the large amount of friction on the elephant would slow it down. The smoother the surface the less friction. ex:/ There will be more friction on a floor of sandpaper than there would be on a floor of ice.
